Activation parameters are determined for the additions of methoxychlorocarbene (MeOCCl) to four alkenes, including tetramethylethylene (TME). MeOCCl is the first carbene to exhibit appreciable activation energy in addition to TME (5.8 kcal/mol), although this reaction is still "dominated" by entropy (-TDeltaS(double dagger) approximately 7 kcal/mol).
确定了将甲氧基氯卡宾(MeOCCl)加到四个烯烃(包括四甲基乙烯(TME))中的活化参数。MeOCCl是除TME(5.8 kcal / mol)外还显示出明显活化能的第一个卡宾,尽管该反应仍被熵“控制”(-TDeltaS(双匕首)约为7 kcal / mol)。
