Abstract

Abstract Metallacycles are formed upon thermolysis of (s-trans-η 4-butadiene) zirconocene and binuclear (η 2-aldehyde) zirconocene complexes or photolysis of diphenylzirconocene in the presence of t-butyl-, trimethylsilyl-, and phenyl-acetylene. From a surprising equally high preference for α-t-butyl-and-trimethylsilyl-substituted products as well as the statistically favoured 2, 4-disubstituted metallacyclopentadienes formed from t-butyl-or trimethylsilyl- ...
