Homologation Of Boronic Esters Research Articles

ChemInform Abstract: Organoboranes. Part 46. New Procedures for the Homologation of Boronic Esters: A Critical Examination of the Available Procedures to Achieve Convenient Homologation of Boronic Esters.

AbstractNine procedures using LiCHCl2 and LiCH2Cl are examined for the one‐carbon homologation of boronic esters.

ChemInform Abstract: Organoboranes. Part 44. A More Convenient, Practical Route to Achieve the Homologation of Boronic Esters.

AbstractAmore practical procedure has been developed for the homologation of boronic esters, utilizing the in situ formation of dichloromethyllithium at ‐78°C from dichloromethane and one of the bases (III) or (IV), followed by in situ reduction of the α‐chloroboronic ester intermediates as shown in the scheme.

Homologation of boronic esters with trimethylsilylchloromethyllithium

Trimethylsilylchloromethyllithium adds to boronic esters to form ate complexes which rearrange with displacement of chloride to form the homologous α-trimethylsilyl boronic esters in high yields.
