Ev. Kudrik et al., 3,6-Didecyloxyphthalonitrile as a starting compound for the selective synthesis of phthalocyanines of the ABAB type, RUSS CHEM B, 49(12), 2000, pp. 2027-2030
Reactions of 3,6-dipentyloxy- and 3,6-didecyloxyphthalonitriles with lithiu
m pentoxide in pentan-1-ol were studied. 3,6-Didecyloxyphthalonitrile can b
e used for the preparation of both the corresponding octasubstituted phthal
ocyanines and phthalocyanines of the ABAB type.
