3-disilacyclobutanes or to polymeric products. A possible intermediate silaalkene could not be stabilized, even in the presence of bulky substituents at the silicon atom. Photolysis of some di- or tri-substituted silacyclobutanes in methanol results in ring opening or in elimination of an alkene with further reaction of the intermediates with the solvent. Photolysis of the 1,1-diphenyl-2-methyl-l-silacyclobutane
某些1,1-二-或1,1,2-三取代的1-silacyclobutanes的热分解导致1,3-disilacyclobutanes或聚合产物。即使在硅原子上存在大量取代基,可能的中间硅烷基烯烃也无法稳定。一些二或三取代的甲硅烷基环丁烷在甲醇中的光解导致开环或烯烃的消除,以及中间体与溶剂的进一步反应。1,1-二苯基-2-甲基-1-硅环丁烷在环己烷中的光解产生1,1,3,3-四苯基-1,3-二硅环丁烷。讨论了硅或碳原子上取代基对反应路径的影响。1,1,3,3-四甲基-2,4-二苯基-1,3-二硅环丁烷的光解反应通过开环和添加甲醇而发生,而1,1,3,3-四苯基-1,
