A novel chemiluminescence from the reaction of 9-arylmethylene-10-methyl-9,10-dihydroacridines and peroxyacid
摘要:
Reaction of 9-arylmethylene-10-methyl-9,10-dihydroacridine (1) with more than two equivalents of m-choloroperoxybenzoic acid in CH2Cl2 affords intermediary beta-hydroxy-tertiary-alkyl peroxyester (5) decomposing to N-methylacridone and aromatic aldehyde with chemiluminescence by a CIEEL mechanism.

Nucleophilic ringopening of oxiranes 1 and 2 by the carbanion AH− (“anthracene hydride”) proceeds rapidly giving rise to two isomeric products 3 and 5 from styreneoxide 1. In prolonged reactions, products with a 9-benzyl 9,10-dihydroanthracene structure (5, 6) are fragmented by an excess of carbanion to yield anthracene A and benzylic anions. The respective products 7 and 8 of reductiveopening can be

Investigations of electron transfer reactions in donor-spacer-acceptor (DSA) molecules posessing small numbers of reactive conformations have significantly increased understanding of factors that control transfer rate constants. The syntheses of polynorbornane-based DSA molecules 12, 16, 20, 26, 30, and 34 and heptacyclotetradecane-based DSA molecules 40, 47, 51, and 60 are described. These molecules have been used to explore the effects of electronic symmetry, solvent electronic structure, and temperature on photoinduced electron transfer reactions.
