Abstract
Bis(pentachlorophenyl)diazomethane (1a) was prepared, and reactivities of perchlorodiphcnylcarbene (2a) generated by photolysis of 1a were investigated not only in terms of product analysis but also by using flash photolysis techniques. Although the major reaction found for 2a was dimerization forming perchlorotetraphenylethylene and was essentially similar to that observed for 2,2',4,4',6,6'-hexachlorodiphenylcarbene (2b), product distribution clearly indicated that the carbenic center in 2a is more rigidly protected than that in 2b by the four ortho chloro substituents which are buttressed by the four meta chloro groups
