Abstract: 1,2,3-Tricyanobenzene can be prepared in a good yield from fluorobenzonitriles by reaction with an alkali metal cyanide. This product can be converted into metal-free tetracyanophthalocyanines or into the corresponding metal complexes by tetramerisation, if appropriate in the presence of metals or metal compounds. These products are excellent organic pigments.

Abstract: Metal-free phthalocyanines in the .chi.-modification substituted in up to four ortho positions can be prepared by tetramerisation of a reaction mixture consisting of phthalonitriles substituted in the 3-position with phthalonitrile in a molar ratio of 4:0 to 1:40 in the presence of a base and subsequent heat treatment at temperatures of between 100.degree. and 300.degree. C. They constitute excellent organic pigments.

Abstract: 2-Thiazolyl tetrazolium salt compounds characterized by a reflectance spectrum exhibiting an extended plateau above about 600-650 nm. Such compounds are useful as chromogenic indicators for reducing substances such as NADH. The reflectance plateau confers improved accuracy to analytical assays, particularly for the determination of analytes of medical diagnostic significance, in which a colorimetric response on a reagent carrier matrix is measured by reflectance.
