of 1,3,5-hexatriene (I) with trimethylsilyl chloride and magnesium affords 74% disilylhexadienes, consisting of 8% 1,4-bis(trimethylsilyl)-2,5-hexadiene (II) and 92% 1,6-bis(trimethylsilyl)-2,4-hexadiene (III). The isomers IIIa, IIIb and IIIc can be separated via the Dieis—Alder adducts. Maleic anhydride reacts with IIIa and IIIb to give the bis[(trimethylsilyl)methyl] derivatives of 4-cyclohexene-1
1,3,5-己三烯(I)与三甲基氯硅烷和镁的还原甲硅烷基化反应可得到74%的二甲硅烷基己二烯,其中8%的1,4-双(三甲基甲硅烷基)-2,5-己二烯(II)和92% 6-双(三甲基甲硅烷基)-2,4-己二烯(III)。异构体IIIa,IIIb和IIIc可通过Dieis-Alder加合物分离。马来酸酐与IIIa和IIIb反应,得到4-环己烯-1,2-二碳原子羧酸酐的双[((三甲基甲硅烷基)甲基]衍生物(IVa和IVb),而IIIc不与马来酸酐反应。通过还原甲硅烷基化反应,3-甲基-1,3,5-己三烯(V)得到1,6-双甲硅烷基化的2,4-己二烯VIa和VIb,其与马来酸酐得到加合物VIIa和VIIb。
