Synthesis, characterization and aquation kinetics of a new trans diastereoisomer of dichloro(meso-5,12-dimethyl-1,4,8,11-tetraazacyclotetradecane)cobalt(III) perchlorate
Abstract
A new trans diastereoisomer of dichloro(meso-5,12-dimethyl-1,4,8,11 -tetraazacyclotetradecane)-cobalt(m) 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 1H and 13C 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.
