Photochemical reactions of quinones with allylstannanes provided four types of products: adducts of allyl group to the carbonyl oxygens of quinones, adducts of allyl group to the olefinic carbons, adducts of allyl group to the carbonyl carbons, and hydroquinones.An electron-transfer mechanism was confirmed by 1H-CIDNP (Chemically Induced Dynamic Nuclear Polarization) method.This study suggests that a) photoinduced electron transfer from allylstannanes to quinones produces the corresponding quinone anion radicals and tin cation radicals, b) the tin cation radicals cleave to give allyl radicals as well as tin cation, and c) the allyl radicals attack the quinone anion radicals resulting in the formation of final products, allylated quinones.
