A simple rhodium-catalyzed addition reaction of aldehydes with arylboronic acids in aqueous ?-valerolactone

摘要

A simple rhodium-catalyzed addition reaction of aldehydes with arylboronic acids in aqueous g gamma-valerolactone provides the corresponding benzylic alcohols in moderate to good yields. Other organoboron reagents (boronic esters, aryltrifluoroborates, etc.) also showed good compatibilities, albeit with relatively lower yields.
