Abstract

Time-resolved electronic absorption spectroscopy has been successfully applied to clarify the mechanism of the “abnormal” photochemical cleavage of 4-nitrophenyl piperidinoalkyl ethers induced by controlled Coulombic disturbance of the “normal” electronic distribution of the radical anion intermediate. Thus, photolysis of 1-piperidino-2-(2-methoxy-4- nitrophenoxy) ethane (a system with an amine with limited freedom of motion) in ...
