“…The frequencies of the C-H deformation vibrations are strongly, those of the C-C1 vibrations only weakly lowered. This model replaces models B and C described in our earlier publication [9]. It should be noted also that the critical energy E~l,l, which is now in agreement with all our work, is 16 kJ/mol higher than E02,3, and this difference should be approximately equal to the difference in Arrhenius activation energies for the two processes.…”

Abstract1,l-Dichlorocyclopropane has been produced by addition of CHz('A1) to 1,l-dichloroetbylene. CHZ('A1) was generated by the photolysis of ketene at 277-334 nm. The 1,l-dichlorocyclopropane was formed in a chemically activated state, had an energy content between 386 and 400 kJ/mol, and reacted in two parallel channels to 2,3-dichloropropene and 1,ldichloropropene. 1,l-Dichloropropene was also formed directly by insertion of CHZ('A1) into the CH bond of 1,l-dichloroethylene. As secondary reactions elimination of HCl from chemically activated 2,3-dichloropropene occurred with 3-chloropropyne and chloroallene as products. In some of the experiments perfluoropropane was added as an inert gas. The apparent rate constants for the isomerization and elimination reactions are reported. The results of RRKM calculations including distribution functions for the activated 1,l-dichlorocyclopropane and a step-ladder model for the deactivation verify the proposed reaction scheme.

Chlorocyclopropane has been produced by addition of CH2(1AJ and CH2(3B,) to chloroethene. CH2 was generated by the photolysis of ketene at 313 and 366 nm. Chlorocyclopropane was formed in a chemically activated state, had an energy content between 378 and 427 kJ/mol, and reacted in three parallel channels to 3-chloropropene, cis-and trans-1-chloropropene. As secondary reactions elimination of HCl from the chemically activated primary products occurred to form allene and propyne. The apparent rate constants for the isomerization and elimination reactions are reported. The results of FtRKM calculations including distribution functions for the activated chlomyclopropane and a stepladder model for the deactivation support the proposed reaction scheme.
