Iridium(iii)-catalyzed photoredox cross-coupling of alkyl bromides with trialkyl amines: access to α-alkylated aldehydes
摘要:
A C(sp3)–C(sp3) cross coupling approach based on an iridium-photocatalytic radical process has been developed for the synthesis of α-alkylated aldehydes from alkyl bromides and trialkyl amines.
Herein, a new method has been developed for the synthesis of various α‐hydroxyacetophenones via an electro‐oxidation process. It involves electrocatalytic hydroxylation via debromination of C(sp3)‐Br bond. Here, simultaneous breaking of carbon‐bromine (C‐Br) bond and formation of a new carbon‐oxygen (C‐O) bond has been achieved through electrolysis of H2O using binary mixture of water and DMSO. The protocol
