The photochemical reaction of disilirane with unsaturated compounds such as
nitrile, ketone and aldehyde in the presence of C-60 with a halogen lamp (
cutoff <400 nm) affords the corresponding adducts of disilirane and unsatur
ated compounds as bis-silylated products. The experimental results by using
laser hash photolysis technique confirm the formation of the adducts via a
photoinduced electron transfer process between 1 and 3C(60)*. I, this bis-
silylation reaction, C-60 serves as a sensitizer. (C) 2000 Elsevier Science
