A synthetic method for the preparation of azo dyes with strong electron acceptor groups has been developed.

The syntheses of 2,4,6-tris(1-naphthyl), (2-methylphenyl), and (4-dibenzofuranyl)mesitylene are described, and evidence for their existence as stereoisomeric mixtures is presented.

We report the synthesis and structural characterization of a new oxoanion halide, NaCa sub 2 GeO sub 4 F. Crystal data: FW=235. 74, Pnma (No.

Synthesis, properties and reactions of two isomeric dipyrido-1,4-dithiins of the C-2h and C-2v symmetry are described.

The isomeric diazadithiapentacenes (3) and (4) were obtained in re-actions of 2-chloro-3-bromoquinoline (5) with selected sulfur reagents in various conditions.
