The correlations between electron impact induced formation of fragment [M C 6 H 6 ] + ˙ from alkyl‐substituted 2,2‐diphenyl‐1,3‐dioxa‐2‐germacyclohexane (1) and the peculiarities of the molecular structures were found. Benzene elimination is regiospecific and stereoselective, resulting from the abstraction of an axial phenyl group and a hydrogen atom from the C‐4 or C‐6 position of the ring.
