2-disila-4-cyclohexene were obtained in near equal quantities from the reaction of 1,3-butadiene with Si2H4 (H3SiSiH or H2SiSiH2) generated from the pyrolysis of Si3H6. Competitive reactions of SiH2 with 1,3-butadiene and Si2H6 and of GeH2 with 1,3-butadiene and digermane have demonstrated that while SiH2 addition to 1,3-butadiene can compete favorably with insertion into Si2H6, GeH2 addition to 1,3-butadiene
通过
1,3-丁二烯与由乙
硅烷热解产生的SiH 2,ClSiH和CH 3 SiH反应获得Sila-3-
环戊烯。由
1,3-丁二烯的有Si的反应在接近等量得到1- Silylsila -3-
环戊烯和1,2-二
硅杂-4-
环己烯2 ħ 4(H 3 SiSiH或H 2 SiSiH 2)产生由Si 3 H 6的热解得到。SiH 2与
1,3-丁二烯和Si 2 H 6的竞争反应以及GeH 2与
1,3-丁二烯和狄格曼的竞争反应表明,SiH 2除了
1,3-丁二烯之外的GeH 2与插入到Si 2 H 6中可以有利地竞争,除了
1,3-丁二烯之外的GeH 2与Ge 2 H 6插入也没有竞争。
