T. Nyokong et J. Guthriestrachan, KINETICS OF THE REACTION OF CYANIDE WITH RUTHENIUM PHTHALOCYANINE COMPLEXES, Inorganica Chimica Acta, 208(2), 1993, pp. 239-242
Kinetic studies of the reaction of cyanide with (CO)(DMF)RuPc and (DMS
O)2RuPc in DMF are reported. In the presence of a large excess of cyan
ide, the (CN)2RuPc complex is formed by pseudo first order kinetics. T
he reaction is first order in both cyanide and phthalocyanine, with sp
ecific rate constants of 5.2 x 10(-2) and 7.2 x 10(-2) M-1 s-1 for rea
ctions of cyanide with (CO)(DMF)RuPc and (DMSO)2RuPc, respectively. Th
e rate constants correspond to the coordination of the second cyanide
ligand to the ruthenium phthalocyanine species.
