摘要
New (E)-styryl-alkynylsubstituted silicon compounds having the generalized formula 1 and A new method of obtaining (E)-styryl-alkynylsubstituted silicon compounds having the generalized formula 1.; ;A denotes: phenylmethylsilyl, 1,4-bis(dimethylsilyl)benzene, 1,2-bis(dimethylsilyl)ethane, 1,1,3,3-tetramethyldisilazane, 1,1,3,3-tetramethyldisiloxane, R′ denotes: tri(isopropyl)silyl, 1-pentyl, 2-(trimethylsiloxy)-2-butyl, 1-(trimethylsiloxy)-1-cyclohexyl, triethylgermyl, R′ denotes: H or Cl and when A denotes phenylmethylsilyl then R″ denotes also methyl or a methoxy group. A method of obtaining (E)-styrylalkynylsubstituted silicon compounds having the generalized formula 1 where A, R′ and R″ denote the same as stated above by way of a silylative coupling reaction between a suitable substituted styrene and a suitable vinyl-alkynylsubstituted silicon compound in the presence of a ruthenium(II) complex as catalyst.
