4,4′-Dianilino-3,3′-(4-chloro­benzyl­idene)bis­[furan-2(5H)-one]

In the mol­ecule of the title compound, C27H21ClN2O4, the dihedral angle between the furan rings is 67.00 (3)°. The chloro­phenyl ring is oriented at dihedral angles of 76.61 (3) and 69.36 (3)° with respect to the furan rings. An intra­molecular N—H⋯O inter­action results in the formation of an eight-membered ring with a twisted conformation. In the crystal structure, inter­molecular N—H⋯O and C—H⋯O inter­actions link the mol­ecules into a three-dimensional network, forming R 2 2(16) ring motifs. Three weak C—H⋯π inter­actions are also found

Adding value to endogenous resources: spicy chestnut bits and salty chestnut crackers... Wanna a bite?

Two new products were created to address the challenge of promoting the nut value chain. The spicy chestnut appetizers involve baking frozen chestnuts with spices to create a warm or room-temperature snack. The salty chestnut flour cookies incorporate chestnuts and spices into a modified recipe for a savoury treat.Os autores agradecem à Fundação para a Ciência e a Tecnologia (FCT, Portugal) e ao FEDER no âmbito do programa PT2020 pelo apoio financeiro ao CIMO (UID/AGR/00690/2019).info:eu-repo/semantics/publishedVersio

Synthesis and reactions of donor cyclopropanes: efficient routes to cis- and trans-tetrahydrofurans

A detailed study on the synthesis and reactions of silylmethylcyclopropanes is reported. In their simplest form, these donor-only cyclopropanes undergo Lewis acid promoted reaction to give either cis- or trans-tetrahydrofurans, with the selectivity being reaction condition-dependant. The adducts themselves are demonstrated to be an important scaffold for structural diversification. The combination of a silyl-donor group in a donor-acceptor cyclopropane with novel acceptor groups is also discussed

Solvothermal synthesis and thermoelectric properties of indium telluride nanostring-cluster hierarchical structures

A simple solvothermal approach has been developed to successfully synthesize n-type α-In2Te3 thermoelectric nanomaterials. The nanostring-cluster hierarchical structures were prepared using In(NO3)3 and Na2TeO3 as the reactants in a mixed solvent of ethylenediamine and ethylene glycol at 200°C for 24 h. A diffusion-limited reaction mechanism was proposed to explain the formation of the hierarchical structures. The Seebeck coefficient of the bulk pellet pressed by the obtained samples exhibits 43% enhancement over that of the corresponding thin film at room temperature. The electrical conductivity of the bulk pellet is one to four orders of magnitude higher than that of the corresponding thin film or p-type bulk sample. The synthetic route can be applied to obtain other low-dimensional semiconducting telluride nanostructures
