T. Kusukawa et al., UNUSUAL REARRANGEMENT IN THE PHOTOCHEMICAL ADDITION OF BIS(ALKYLIDENE)DISILACYCLOBUTANES TO C-60, Organometallics, 13(11), 1994, pp. 4186-4188
The photochemical reaction of bis(alkylidene)disilacyclobutanes 1a,b w
ith C-60 afforded the stable 1:1 adducts 3a,b, resulting from an unexp
ected rearrangement of the disilacyclobutane unit. The structures of 3
a,b were determined by spectroscopic methods, including Si-29-H-1 HMBC
hetero nuclear shift correlation experiments.
