โœฆ Synopsis

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.
