Abstract

5 radical intermediateb) seems to be as much as 15 times more rapid than cl~sure,~ the validity of any model that ignores the complex set of rate constants involved in photochemical cycloadditions is suspect. X-ray Analysis. The structure of compound 5 was unambiguously established by a routine single-crystal X-ray analysis. Crystals of this compound belonged to the monoclinic space group P2,/c with a = 13.590 (3), b = 20.706 (3), c = 6.670 (1) A, p = 106.50 (1)O. The ...
