New Applications of Solid Silica Chloride (SiO 2 -Cl) in Organic Synthesis. Efficient Preparation of Diacetals of 2,2-Bis(Hydroxymethyl)-1,3-propanediol from Different Substrates and Their Transthioacetalization Reactions. Efficient Regeneration of Carbonyl Compounds from Acetals and Acylals
Nickel-Catalyzed One-Pot Deoxygenation and Reductive Homocoupling of Phenols via C–O Activation Using TCT Reagent
A new method for C–O bond
activation of phenolic compounds has been achieved using 2,4,6-trichloro-1,3,5-triazine
to utilize in one-pot Ni-catalyzed deoxygenation and reductive homocoupling
reactions. With this simple method, phenolic compounds were converted
to their corresponding arenes or biaryl compounds under mild conditions.
The introduced methodology has a broad scope and demonstrates good
functional group compatibility
A New Approach to the Reduction of Sulfoxides to Sulfides with 1,3-Dithiane in the Presence of Electrophilic Bromine as Catalyst
1,3,2,4-Diazadiphosphetidine-based phosphazane oligomers as source of P(III) atom economy reagents: Conversion of epoxides to vic
Nickel-Catalyzed Deoxycyanation of Activated Phenols via Cyanurate Intermediates with Zn(CN)<sub>2</sub>: A Route to Aryl Nitriles
A novel, and efficient
nickel-catalyzed deoxycyanation of phenolic
compounds using relatively nontoxic ZnÂ(CN)<sub>2</sub> as the cyanide
source was developed. The reaction of C–O bond activated phenolic
compounds by 2,4,6-trichloro-1,3,5-triazine with ZnÂ(CN)<sub>2</sub> in the presence of a nickel precatalyst afforded the aromatic nitriles
in good to excellent yields
1,3,2,4-Diazadiphosphetidine-based phosphazane oligomers as source of P(III) atom economy reagents: Conversion of epoxides to <i>vic</i>-haloalcohols, <i>vic</i>-dihalides, and alkenes in the presence of halogen sources

Efficient Conversion of Tetrahydropyranyl (THP) Ethers to Their Corresponding Thiocyanates With in-situ–Generated Ph 3
Nickel-Catalyzed Reductive Etherification of Aldehydes at Room Temperature: C–O vs C–C Bond Formation
The reaction of secondary and tertiary
benzyl alcohols activated
by 2,4,6-trichloro-1,3,5-triazine (TCT) with aldehydes in the presence
of NiCl<sub>2</sub>·dmg as a precatalyst in ethylene glycol afforded
ethers at room temperature. A selective C–O vs C–C bond
formation was observed for the secondary and tertiary benzyl alcohols
in comparison with primary ones
