✦ Synopsis

The condensation of substituted diiminoisoindolines with phthalocyanines 23 and 25 possessing isobenzofuran moieties as diene subunits was accomplished; in the alkyl-substituted 1,3,3-trichloroisoindolines results in the formation of the highly soluble metal-free phthalocyanines 9, presence of excess 28, the tetracyclone-bisadducts 22 and 24

were transformed into the model compounds 29 and 30, 15.

By the same methodology, metal-containing phthalocyanines such as 16, 18 are accessible from suitable while an excess of 20 or 9 leads to the appropriate trimeroligomers 31 and 32. metal salts. The precursors 24 and 26 were obtained from the phthalocyanine 9 and tetracyclone. The generation of the six different phthalocyanines which are always formed in [

## Abstract The reaction of 5‐bromomethyl‐3‐(__p__‐bromomethylphenyl)isoxazole with __o‐, m‐__, and __p__‐bis(mercap‐tomethyl)benzenes gave the corresponding dithia‐ and/or tetrathiaisoxazolophanes, whose relative yields strongly depended upon the nature of the mercaptomethyl compound. The above is
