The energy of activation for ring-closure of ground state triplet trimethylenemethane (I) to methylenecyclopropane has been measured by following the rate of dissappearance of the electron spin resonance spectrum over the temperature range –155° to –140°, in a series of frozen solid matrices. The experiments described make use of 3-methylenecyclobutanone and methylenecyclopropane as precursors to
在一系列冷冻过程中,通过跟踪电子自旋共振谱在–155°至–140°温度范围内消失的速率,测量了基态三重态三甲撑甲烷(I)闭环成亚甲基环丙烷的活化能。固体矩阵。所描述的实验利用3-亚甲基环丁酮和亚甲基环丙烷作为三亚甲基甲烷的前体。
