Synthesis of polysilanes by reductive coupling of dichlorosilanes mediated with alkali metal crown ether supramolecular complexes in a homogeneous system
Structure and properties of poly(methylphenylsilane) synthesized by reductive coupling of silyl halides with alkali metal supramolecular complexes: (Mt(+)/18-crown-6, Mt(-), where Mt = K, Na; 18-crown-6 = 1,4,7,10,13,16-hexaoxacyclooctadecane) were investigated. The coupling process yields polymers exhibiting narrow molecular weight distribution and number-average molecular weights up to 8 500, cyclic oligomers being formed along with linear ones.
