摘要
Chemically Induced Dynamic Nuclear Polarization (CIDNP) technique is applied to study the photochemical reactions of 1-acetylindole-2,3-dione (AID) with several hydrogen do- nors (1—13). These reactions take place by direct hydrogen abstraction of triplet excited AID from the corresponding 1—13 to give neutral radical pair intermediates, which afford polarized starting materials by back hydrogen transfer and give polarized coupling products by radical pair recombination.
