Abstract

4, 41 (1971);(d) PG Bauslaugh, Synthesis, 287 (1970).(17) We have not been able to detect phosphorescence from nr* excit-ed 9 in methylcyclohexane at 77 K and thus there is no direct evidence for the generation of n-r'triplets. However, since there are ample examples in which phosphorescence was not observed from nr* triplets of a,@-unsaturated ketones, and since most of the photoaddition reaction of a,@-unsaturated ketones is known to involve n ...
