Abstract
Abstract Highly inert to ionic additions to aldehydes, aryl-and 1-alkenylboronic acids succumb to a catalytic variant mediated by a [Rh (acac)(CO) 2]–diphosphane complex in aqueous phase at 80–95 C to yield secondary alcohols [Eq.(a)]. A key step in the catalytic cycle is the transmetalation between the boron reagent and the rhodium complex. L n= diphosphane (eg 1, 1′-bis (diphenylphosphanyl) ferrocene); R= aryl, 1-alkenyl; R′= ...
