摘要：

The reactions of bis-(bromomagnesiummethyl) carboranes with dimethyldimethoxysilane were studied. It has been shown that interaction of 1,2-bis-(bromomagnesium)-o-carborane with an excess of dimethyldimethoxysilane gives the mixture of 1,2-(methoxydimethylsilylmethyl)-o-carborane and exocyclic 1,2-(o-carboranyleno)-4,6-bis-(dimethylsilyl)-5-oxa-cycloheptane. In the case of 1,7-bis-(bromomagnesiummethyl)- m-carborane, only 1,7-bis-(methoxydimethyl-silylmethyl)-m-carborane is formed. The possibility of obtaining Grignard reagents from 1,2 (7)-(bromomethyl)-o(m)-carboranes has been established. (C) 2017 Elsevier B.V. All rights reserved.
