Hydrodebromination of allylic and benzylic bromides with water catalyzed by a rhodium porphyrin complex?
Dalton Transactions Pub Date: 2018-08-16 DOI: 10.1039/C8DT02168F
Abstract
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.
