Effect of the nature of nitrogen-containing bases on their catalytic activity in the reaction of zinc compleх formation with tetra(4-<i>tert</i>-butyl-5-phenylsulfanyl)phtalocyanine in benzene

Abstract

The catalytic action of the cyclic and acyclic organic nitrogen bases on the complex formation between zinc and tetra(4- tert -buthyl-5-phenylsulfanyl)phtalocyanine in benzene was studied. The acid-base interaction was shown to precede the complexation and to play a key role in it. The scheme of complex formation of zinc with tetra(4- tert -buthyl-5-phenylsulfanyl)phtalocyanine in the system containing also organic nitrogen base and benzene was given. The relationship between catalytic activity of the base and its ability to accept proton as well as structure was described.
