Abstract

Arylboronic acid derivatives are versatile intermediates in organic synthesis because of their broad availability, air stability, and ease of handling.[1] Among the routes to arylboronic acid derivatives, the conventional methods that use aryllithium or Grignard reagents have a problem with functional-group compatibility. More recently, functionalgroup-tolerating approaches such as the transition-metalcatalyzed borylation of aryl halides [2, 3] and the ...
