Abstract

Photoirradiation at a wavelength of> 300 nm of a deaerated suspension of cadmium (II) sulfide (CdS) particles in an aqueous solution of a mixture of stereoisomers of 2, 6- diaminopimelic acid (DAP;(S, S)∶(R, S)∶(R, R)= 1∶ 2∶ 1) produced piperidine-2, 6- dicarboxylic acid (PDC) via a redox-combined mechanism including oxidation and reduction by positive holes and photoexcited electrons, respectively. Both the yield and trans∶ cis ...
