摘要：

Readily accessible from bis(propynyl)zirconocene, the organometallic betaines like 1 form by an intramolecular alkyne insertion and trapping reaction with tBuNC from an intermediate that has a hexadiyne ligand unsymmetrically coordinated to the Zr and B centers. This diyne complex is obtained in a rapid CC coupling reaction reaction between the starting material and B(C6F5)3. (Figure Presented.) Copyright © 1994 by VCH Verlagsgesellschaft mbH, Germany
