A NEW SERIES OF ORGANOBORANES. VII. THE PREPARATION OF POLY-M-CARBORANYLENESILOXANES,

Abstract

The following meta-carboranylene backboned polysiloxanes were obtained by ferric chloride catalyzed polymerizations: (-Si(CH3)2CB10H10CSi(CH3)2O-) from 1,7-bis(chlorodimethylsilyl)m-carborane plus bis (methoxydimethylsilyl)m-carborane; (I); (-Si(CH3)2CB10H10CSi(CH3)2OSi(CH3)2O-) from dichlorodimethylsilane (II) plus I; (-Si(CH3)2CB10H10CSi(CH3)2OSi(CH3)2OSi(CH3)2O-) from a dimer of II plus I; (Si(CH3)2CB10H10Si(CH3)2OSi(CH3)2OSi(CH3)2O-) from dilitho-m-carborane plus dichlorotetramethyldisiloxane. These compounds, and a number of substitution products thereof, were examined by X-ray diffraction and their thermal and oxidative behavior were studied by differential calorimetry.
