Synthesis of carborane-fused carbo- and heterocycles via zirconacyclopentane intermediates

Author affiliations

Abstract

A variety of carborane-fused carbo- and heterocycles were prepared in good to high isolated yields via the reaction of carborane-fused zirconacyclopentane with a series of substrates such as S8, Se, Te, CO, XylNC, MeOOC–CH[double bond, length as m-dash]N2, PhPCl2, nBu2SnCl2 and Me2GeCl2. However, it was found that the Zr–C bond in the zirconacyclopentane did not show any reactivity towards PhBCl2, PhCN and PhCH[double bond, length as m-dash]NPh. This approach represents a promising route to functionalized carboranes that are difficult to access by conventional methods.
