摘要
Thermal reduction of 10-methylacridinium ion by allylic stannanes occurs via a polar mechanism to yield the dihydroacridines allylated at the gamma-position exclusively, while the photoallylation of 10-methylacridinium ion proceeds via the photoinduced electron transfer from allylic silanes and stannanes to the singlet excited state of 1 0-methylacridinium ion to yield mainly the alpha-adducts.
