摘要

Abstract: A study of stereochemical and mechanistic aspects of the di-*-methane rearrangement using 2-phenylspiro [5.5] undeca-1, 7-diene (6) is reported. The sole product of direct irradiation of 6 is 1 l-phenyltricycl0 [5.4. 0.0~~~~] undec-2-ene (7). The spirodi-a- methane 6 was unreactive under triplet-sensitized irradiation conditions which employed both benzophenone and acetophenone. This inertness is due to an unreactive triplet- ...
