SYNTHESIS, CHARACTERIZATION AND AQUATION KINETICS OF A NEW TRANS DIASTEREOISOMER OF DICHLORO(MESO-5,12-DIMETHYL-1,4,8,11-TETRAAZACYCLOTETRADECANE)COBALT(III) PERCHLORATE

摘要

[[abstract]]A new trans diastereoisomer of dichloro(meso-5,12-dimethyl-1,4,8,11-tetraazacyclotetradecane)cobalt(III) perchlorate has been prepared, and the electronic absorption and infrared spectral data studied. The assignments of the structure of the isomer have been accomplished by thorough stereochemical analysis combined with H-1 and C-13 NMR spectral data. Aquation kinetics have been studied at various temperatures and activation parameters determined. The results indicate a dissociative activation with retention of configuration and a distorted-square pyramidal activated complex
