Abstract

Abstract: All six dimethoxyfluorenones 6a–f and dihydroxyfluorenones 7a–f, wherein substitution occurs at only one aromatic ring, were conveniently prepared by palladium (0)- catalyzed cross-coupling reactions of aryl bromides/triflates 2a–e with in situ generated arylboranes, derived from o-bromobenzamide 1a and o-bromophenyloxazoline 1b. Key words: dimethoxyfluorenone, dihydroxyfluorenone, in situ Pd (0) cross-coupling, ...
