Abstract
Ordered tetrazaporphins prepared from the reaction of an aminoiminosubstituted pyrroline with a trihalosubstituted pyrroline in the presence of an acid acceptor and a hydrogen donor. These compounds are useful as intermediates in the preparation of dyes and pigments, as well as dye developers for photographic processes.
Claims14
A phthalocyanine compound of the formula:
- ##STR36## wherein M and Z comprise the atoms necessary to complete carbocyclic rings attached directly to the pyrrolenine ring and wherein M and Z are different ring structures, both being selected from the group consisting of ##STR37##
The compound ##STR38##
The compound ##STR39##
A process which comprises reacting a compound of formula:
- ##STR40## with a compound of the formula:
- ##STR41## in the presence of an acid acceptor and a hydroquinone compound which can donate hydrogen atoms and wherein M.sub.a, M.sub.b, Z.sub.a, and Z.sub.b comprise a hydrogen atom, an aliphatic moiety selected from the group consisting of alkyl, alkenyl and alkynl groups having no more than 6 carbon atoms inclusive, wherein M.sub.a is the same as M.sub.b and Z.sub.a is the same as Z.sub.b, and M.sub.a taken together with M.sub.b and Z.sub.a taken together with Z.sub.b can also comprise the atoms necessary to complete carbocyclic or heterocyclic ring structures attached directly to the pyrrolenine ring which ring structures are selected from the group consisting of unsubstituted, lower alkylsubstituted, lower alkoxysubstituted, and halosubstituted rings, and each X is a halogen atom.
A process which comprises reacting an aminoiminoisoindolenine of the formula:

A process which comprises the step of reacting an aminoiminoisoindolenine with a trihaloisoindolenine in the presence of an acid acceptor chosen from the group consisting of triethyl amine, sodium bicarbonate and calcium oxide and a hydroquinone compound which can donate hydrogen atoms and wherein said aminoiminoisoindolenine is chosen from the group consisting of:
- ##STR45## and wherein said trihaloisoindolenine is chosen from the group consisting of:
- ##STR46##
