Mechanism calculation on the decomposition of 1, 1-dimethyl-1, 2, 2, 2-tetrachlorosilane catalized by AlCl3(AlCl3催化1,1-二甲基-1,2,2,2-四氯二硅烷裂解机理的计算)

采用密度泛函(B3LYP)及二级微扰(MP2)方法对AlCl3催化1,1-二甲基-1,2,2,2-四氯二硅烷裂解反应的机理进行了计算.结果表明,该二硅烷在三氯化铝催化剂作用下可以同时按2种通道进行裂解.裂解反应分3步进行,通道1的速控步为第3步,其活化能为241.656 kJ • mol-1.通道2的速控步为第1步,其活化能为250.227 kJ• mol-1.从速控步的活化能可知,2种反应通道进行的难易程度相差不大.裂解反应为放热反应,反应的理论产率较高....
