摘要：
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.
