The photochemical reaction of 3,4-benzo-1,2-disilacyclobutene 1 with C60 afforded stable 1:1 adduct 2 with C(2v) symmetry. The photochemical reaction of cyclotetrasilane 4a with C60 afforded adducts 5a and 6a, the latter was obtained from a rearrangement of the cyclotetrasilane unit. Similarly, cyclotetragermanes, 4c, gave 5c and the rearranged product 6c. In the case of cyclotrasilane 4b, only the rearranged product 6b was obtained in high yield. The structure of all compounds were determined by spectroscopic methods, including 29Si-1H HMBC hetero nuclear shift correlation experiments.
