Hydrodebromination of allylic and benzylic bromides was successfully achieved by a rhodium porphyrin complex catalyst using water as the hydrogen source without a sacrificial reductant. Mechanistic investigations suggest that bromine atom abstraction via a rhodium porphyrin metalloradical operates to give the rhodium porphyrin alkyl species and the subsequent hydrolysis of the rhodium porphyrin alkyl species to a hydrocarbon product is a key step to harness the hydrogen from water.
NOVEL REACTIONS OF PHOSPHONIUM YLIDES WITH PERHALOALKANES: FIRST EXAMPLES OF HALOPHILIC ATTACKS BY PHOSPHONIUM YLIDES AND A FACILE ROUTE TO α-HALOALKYLPHOSPHONIUM SALTS

Phosphonium ylides Ph3=CHR (R = H, CH3, C2H5, n-C3H7, n-C5H11) react readily with perhalofluoroalkanes to afford regiospecifically α-haloalkylphosphonium salts Ph3P+-CHXR Y- (X = I, Br, Cl) in good yields.These reactions reveal a new type of reactivity phosphonium ylides, i.e., the halophilic attack on C-X bonds, and may be useful for the regiospecific synthesis of substituted haloolefins via Wittig reaction.
