Abstract

Boron-zirconium 1,1,-dimetallic organic compounds useful in organic synthesis such as the preparation of alpha-borobromanes. The boron-zirconium compounds include boron and zirconiun, and in particular the synthesis, structure and reactivity of E-chlorobis(cyclopentadienyl)- [1-(4,4,5,5-tetramethyl-1,3,2-dioxaborolane-2-yl)-3,3-dimethylbutenyl]zirc onium (IV). The boron-zirconium 1,1-dimetallic compound is used as a polymerization catalyst to polymerize alpha-olefins such as styrene.
