Popis: | Dehydrogenative cross-coupling reactions occurred between phenylsilane and ethynylbenzene in the presence of the metal hydrides, such as LiAlH4, NaAlH4, LiBH4 and LiAlH(Ot–Bu)3 to produce some ethynyl compounds. Phenylsilane and diethynylbenzene produced a highly thermally stable polymer, poly[(phenylsilylene)ethynylenephenyleneethynylene]. The activities and selectivities of the reactions were discussed on the basis of the mechanism involving the alkynylaluminate anion. |
