Rapid incorporation of a difluoroacetate radical into <i>para</i>-quinone methides <i>via</i> radical 1,6-conjugate addition

Abstract

Presented herein is a newly designed strategy that rapidly introduces ethyl difluoroacetate radicals through a dialkylzincs induced radical 1,6-conjugate addition pathway. Besides achieving high yields and excellent functional group compatibility, this protocol allowed the incorporation of a gem-difluoromethylene motif to be accomplished within minutes.
