摘要：

The complexes Tp(Br3)CU(NCMe) (1) and Tp(Ms)Cu (2) catalyze the addition of the :CHCO2Et unit (generated from N2CHCO2Et, EDA) to benzene to give a cycloheptatriene ring, in analogy with the Buchner reaction. When alkyl groups are attached to the aromatic rings, the selectivity of the reaction can be oriented toward addition or, alternatively, to the insertion into an alkyl C-H bond by using 1 or 2, respectively.
