In the past few years, organozinc derivatives have been found to be increasingly useful reagents for carrying out organic transformations. 1 The relatively low reactivity of the carbonzinc bond toward electrophilic reagents has made them ideal precursors to more reactive species via transmetalation reactions2 or Lewis acid-catalyzed addition reactions to carbonyl groups. 3 Consequently, one significant advantage of these reagents is that ...
