PHOSPHATE ESTER HYDROLYSIS PROMOTED BY AN AMIDOPYRIDINE CARBOXYLATE COMPLEX

The purpose of this study was to test the ability of the cobalt complex of ammonium cis-dichloro{2-[N-(2'pyridylmethyl)carbamyl]pyridine-6-carboxylato}cobalt(III), and dichloro(1-(2'-pyridylmethyl)-1,5,9triazacyclododecane)cobalt(III)perchlorate, to act as a promoter of diester hydrolysis. The compound isolated by using metal directed syntheses procedure. The ability of kinetic recorded by Bio-Rad FTS7 spectrometer. Ammonium cisdichloro{2-[N-(2'-pyridylmethyl) carbamyl] pyridine-6-carboxylato} cobalt(III), indicate the active compound to hydrolysis bis(4-nitrophenyl)phosphate (BNPP) with the rate constant (k) = 0.50 × 10 min, while dichloro(1-(2'pyridylmethyl)-1,5,9-triazacyclododecane) cobalt(III) perchlorate, does not promote ester hydrolysis.
