Organometallic Reactions of 1-Ethynyl-1,2-Carborane.
Abstract
Ethynylcarborane has been catalytically trimerized to 1,2,4-tris(1'-1',2'- carboranyl)benzene in high yield. The latter species failed to undergo electrophilic substitution on the aromatic ring. A normal substitution product was obtained from the reaction between Co2(CO8) and ethynylcarborane. The interaction of ethynylcarborane with trans-IrCl(CO)(P(C6H5)3)2 afforded a novel octahedral complex containing sigma-2-carboranylacetylide and sigma-trans-2-carboranylvinyl substituents. Copper(II)-catalyzed oxidative coupling produced 1,4-di-(1'-1.2'-carboranyl)butadiyne in good yield. The latter compound was resistant to addition reactions at the triple bonds. (Author)
