Competing ionic and radical photobehavior has been observed for a number of alkyl halides. The proportion of nucleophilic substitution and reduction products were reported for each halide. Solventeffects of ethylene glycol, triethylamine, and methanol and atmospheric effects of nitrogen, oxygen, and air were studied. The effect of irradiation of the halides with methanol-O-d was reported. The results

[GRAPHICS]The products, kinetics, and activation parameters were determined for the fragmentation-ring expansions of 1-norbornylmethyloxychlorocarbene (11) and 3-noradamantylmethyloxychlorocarbene (17). Products from 11 (in dichloroethane) included 1-chlorobicyclo[2.2.2]octane (9, 56%) and 1-chlorobicyclo[3.2.1]octane (10, 37%); from 17, we obtained I-chloroadamantane (15, 68%) and protoadamantyl chloride (16, 28%).
