Novel intramolecularly electronical donor-acceptor systems of N-(trimethylsilyl teminated enesulfenyl ether)phthalimide (1) and N-(trimethylsilyl teminated nitrogen ether)phthalimide (2) were synthesized. Compounds 1 and 2 were irradiated in methanol and the photoinduced intramolecular single electron transfer provided thiacrown ether (3) and nitrogen crown ether (4) with high yield and high regioselectivity. Structures of compounds 1~4 were characterized by MS, NMR data.
