Abstract

The coupling of dilithio-o-carborane with α, ω-dichlorooligodimethylsiloxanes of type ClSi(CH3)2O[Si(CH3)2O]nSi(CH3)2Cl with n from 1 to 3 has been performed. At a molar ratio of the reagent of 1∶1, the products of the reaction are a five-membered ring compound, 1, 3-o-carboranetetramethyldisiloxane and a cyclodimethylsiloxane, and at a ratio of the reagents of 1∶2, a seven-membered ring compound, 1, 5-o-carboranehexamethyltrisiloxane, and a cyclodimethylsiloxane. Attempts to open the seven-membered o-carboranesiloxane ring thermally or with the aid of acidic catalysts were unsuccessful. Under the influence of nucleophilic reagents, cleavage of the C-Si bond takes place with the splitting away of a silicon atom from the o-carborane nucleus and the formation of an o-carbonate and a cyclodimethylsiloxane.
