2,3-二甲基-1,3-丁二烯合成路线 (共 777 条)
反应条件
in cyclohexane
byproducts: Me3SiSiMe3; Irradiation (UV/VIS); Solns. of (Me3Si)2GePh2 in cyclohexane readily undergo photolysis to diphenylgermylene and hexamethyldisilane, when irradiated by an array of low pressure Hg lamps through quartz vessels.; The yields are obtained by (1)H NMR integration.;
