资源简介：
Catalytic formation of fluorene has been achieved from 2-phenylbenzyl trifluoroacetate via successive C–O and C–H bond cleavage reactions by Pd(OAc)2/PPh3 in 97% yield. This reaction involves the oxidative addition of ester to give (carboxylato)(2-phenylbenzyl)palladium(II) species and deprotonation from the 2-phenylbenzyl group by the cleaved carboxylato group via an internal electrophilic substitution mechanism.
