Abstract

Zirconocene complexes of [2.2]paracylophanes with formal triple bonds in the bridges, corresponding to zirconacyclo-propenes, were synthesized from [2.2]paracylophan-1-ene (1) and 1,9(10)-dibromo[2.2]paracyclophan-1,9-diene (5) via their vinyl lithium derivatives and characterized by spectroscopic methods. The zirconocene-alkyne complexes 7, 9 react with bromine or iodine with loss of the ...
