摘要：

The coupling of various Fischer carbene complexes with o-ethynylbiphenyl and an o-alkynylstyrene derivatives has been examined. In coupling reactions with methylcarbene and cyclopropylcarbene complexes, the major products are derived from C-H or C-C activation processes. In coupling reactions with phenylcarbene complexes, the major products are derived from the Dotz reaction. (C) 2001 Elsevier Science Ltd. All rights reserved.
