Data_Sheet_1_Boundary crossing: an experimental study of individual perceptions toward AIGC.CSV

Artificial Intelligence (AI) Generated Content has made great progress in many fields. Those AI art works gradually reshape contemporary understanding of creativity. The unique creative ability of human beings may also be challenged. This paper takes AIGC as the research object and carries out a grouping experiment based on 240 participants. We found that Anthropomorphism and Autonomy have no effect on the evaluation of AI paintings and AI “painter” identity, but in together their have a combined positive impact on both independent variables. The existence of moderating effect reveals the phenomenon of on-the-spot stimulation similar to the strong effect theory. Meanwhile, the evaluation of paintings positively affects the perception of AI “painter” identity. The subjectivity of AI comes from the double superposition of its external and inner characteristics, which may suggest AI with both human-like appearance and function can be regarded as a person with social role identity.</p

Calcium-Catalyzed Dynamic Multicomponent Reaction

The reversible formation of covalent bonds enabled by the remarkably high Lewis acidity of our calcium-based catalyst system was used for the development of a new type of multicomponent reaction. Accordingly, a pharmacologically interesting bicyclic amine was amplified from a highly efficient dynamic equilibrium. The product is formed with full diastereoselectivity, and as typical for our calcium-catalyzed reactions, precautions for the exclusion of air and moisture are unnecessary

In situ transformation from P phase to μ phase in rhenium-containing single-crystal superalloy during thermal exposure

<p>An <i>in situ</i> phase transformation from P to μ in a rhenium-containing superalloy during high-temperature exposure has been investigated by transmission electron microscopy. The orientation relationship between the phases is found as (1–12)_μ // (1 0 0)_P and [2 4 1]_μ // [0 1 1]_P. An atomic model of the μ/P interface was built to reveal a perfectly coherent interface with lattice misfits of only 0.421 and 1.098%. Considering the small lattice distortions and the similar elemental composition of the phases, it is concluded that the phase transformation from P to μ is favourable.</p

Synergistic H₄NI–AcOH Catalyzed Oxidation of the C_sp³–H Bonds of Benzylpyridines with Molecular Oxygen

The oxidation of benzylpyridines forming benzoylpyridines was achieved based on a synergistic H₄NI–AcOH catalyst and molecular oxygen in high yield under solvent-free conditions. This is the first nonmetallic catalytic system for this oxidation transformation using molecular oxygen as the oxidant. The catalytic system has a wide scope of substrates and excellent chemoselectivity, and this procedure can also be scaled up. The study of a preliminary reaction mechanism demonstrated that the oxidation of the C_sp³–H bonds of benzylpyridines was promoted by the pyridinium salts formed by AcOH and benzylpyridines. The synergistic effect of H₄NI–AcOH was also demonstrated by control experiments

An Effective Method for the Construction of Esters Using Cs₂CO₃ as Oxygen Source

An effective method for the construction of esters from acyl chloride and halohydrocarbon using Cs₂CO₃ as an oxygen source was achieved for the first time. The methodology has a wide scope of substrates and can be scaled up. The study of a preliminary reaction mechanism demonstrated that the O in the products comes from Cs₂CO₃ and this esterification proceeds through a free radical reaction. It was also found that CO₂ can also be used in this esterification reaction as an oxygen source

Selective Oxidation of Unsaturated Alcohols Catalyzed by Sodium Nitrite and 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone with Molecular Oxygen under Mild Conditions

We have developed a simple and practical process for the oxidation of alcohols to the corresponding carbonyl compounds by using a low catalytic amount of DDQ, NaNO₂ as a cocatalyst, and molecular oxygen as terminal oxidant. Nitric oxide generated in situ by NaNO₂ in the presence of AcOH is essential for the realization of the catalytic cycle at room temperature. The practical utility of this catalytic process has been demonstrated in the gram-scale oxidation of cinnamyl alcohol

Asymmetric Epoxidation of Alkenes Catalyzed by a Porphyrin-Inspired Manganese Complex

A novel strategy for catalytic asymmetric epoxidation of a wide variety of olefins by a porphyrin-inspired chiral manganese complex using H₂O₂ as a terminal oxidant in excellent yield with up to greater than 99% ee has been successfully developed

Iron/ABNO-Catalyzed Aerobic Oxidation of Alcohols to Aldehydes and Ketones under Ambient Atmosphere

We report a new Fe­(NO₃)₃·9H₂O/9-azabicyclo­[3.3.1]­nonan-<i>N</i>-oxyl catalyst system that enables efficient aerobic oxidation of a broad range of primary and secondary alcohols to the corresponding aldehydes and ketones at room temperature with ambient air as the oxidant. The catalyst system exhibits excellent activity and selectivity for primary aliphatic alcohol oxidation. This procedure can also be scaled up. Kinetic analysis demonstrates that C–H bond cleavage is the rate-determining step and that cationic species are involved in the reaction

Highly Chemoselective and Enantioselective Catalytic Oxidation of Heteroaromatic Sulfides via High-Valent Manganese(IV)–Oxo Cation Radical Oxidizing Intermediates

A manganese complex with a porphyrin-like ligand that catalyzes the highly chemoselective and enantioselective oxidation of heteroaromatic sulfides, including imidazole, benzimidazole, indole, pyridine, pyrimidine, pyrazine, <i>sym</i>-triazine, thiophene, thiazole, benzothiazole, and benzoxazole, with hydrogen peroxide is described, furnishing the corresponding sulfoxides in good to excellent yields and enantioselectivities (up to 90% yield and up to >99% ee) within a short reaction time (0.5 h). The practical utility of the method has been demonstrated in the gram-scale synthesis of chiral sulfoxide. Mechanistic studies, performed with ¹⁸O-labeled water (H₂¹⁸O), hydrogen peroxide (H₂¹⁸O₂), and cumyl hydroperoxide, reveal that a high-valent manganese–oxo species is generated as the oxygen atom delivering agent via carboxylic acid assisted heterolysis of O–O bonds. Density functional theory (DFT) calculations were also carried out to give further insight into the mechanism of manganese-catalyzed sulfoxidation. On the basis of the theoretical study, the coupled high-valent manganese­(IV)–oxo cation radical species, which bears obvious similarities with that of reactive intermediates in the catalytic oxygenation reactions based on the cytochrome P450 and metalloporphyrin models, has been proposed as the reactive oxidant in the non-heme manganese catalyst system
