摘要：

The photochemical decomposition of 7-sila- and 7-germa-norbornadienes (Ia,b) was studied by the CIDNP 1H technique. The reactions proceeds by a two-step mechanism via the reversible formation of singlet biradicals, II. The triplet biradical (II), formed as a result of S-T conversion of (II)(S), irreversibly decomposes giving Me2E (E = Si, Ge). The insertion of Me2E into the CBr bond of PhCH2Br and the SnCl bond of Me3SnCl occurs via a radical mechanism, as deduced from the CIDNP effects observed in these reactions. © 1990.
