Zinc naphthalocyanine has been prepared in low yield (18%) by the template reaction of Zn(02CMe)2, urea and 2,3-naphthalenedicarboxylic acid.1138 The synthesis of zinc tetra-2,3-naphthoporphine by a template reaction has been described.1139... 

Application of the same methods starting from 1,2-dicyanonaphthalene [11] yields 1,2-naphthalocyaninatometal complexes. The magnesium, lead, copper and zinc 1,2-naphthalocyanines (1,2-NcM) were first prepared by Linstead [12], Compared to the corresponding phthalocyanines the known 1,2-naphthalocyaninatometal compounds exhibit a higher thermal and chemical stability. When 1,2-NcM, is synthesized from 1,2-dicyanonaphthalene four different positional isomers are formed (compare to 2,3-NcM, Fig. 1) [11],...
