    Z-1,4-Disilyl-2-butenes, R3SiCH2CH=CHCH2SiR3 (R3 = Me3, Me2H, Me2(ClCH2), Me2Ph(CH2)3, Me(2-Bu)2 and Et3) have been pre pared in high yields by the re ac tion of 1,4-dilithio-2-butene with the corresponding trialkylchlorosilanes, us ing tert-butyl methyl ether as the solvent. The course of ananalogous reaction of dimethyldichlorosilane is briefly discussed.

    Z-1,4-Disilyl-2-buteny, R3SiCH2CH=CHCH2SiR3 (R3 = Me3, Me2H, Me2(ClCH2), Me2Ph(CH2)3, Me(2-Bu)2 a Et3) byly připraveny ve vysokých výtěžcích reakcí 1,4-dilithio-2-butenu s příslušnými trialkylchlorsilany v terc-butylmethyletheru. Průběh analogické reakce s dimethyldichlorsilanem je také diskutován.
