Abstract:
We reported the synthesis and characterization of a novel vanadium hydride complex {[DippN2NCH2C6H4]VH}2{K}2 (2) obtained through intramolecular Caryl-H oxidative addition with an in situ-generated low-valent vanadium intermediate. This vanadium hydride exhibits strong reducing properties and is capable of activating O2 through a 4-electron reduction process. Simultaneously, it forms dioxovanadate complex 5 with a regenerated Csp2-H bond and oxovanadium complex 6. Feasible mechanisms for the formation of 5 and 6 were proposed based on the deuterium-labeled experiments and DFT calculations.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat...
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
