Rhodacyanines possess two chromophoric systems. They are at the same time neutrocyanine derivatives, which involves position 5 of the ketomethylene, and methine cyanine, which involves position 2. Following lUPAC s standard nomenclature rules, structure 7 is named 3-ethyl-4-phenyl-2- 4-oxo-3-ethyl-5-[2-(3-ethy]-2,3-dihydro-benzo-l,3-thiazo-lylidene)ethylidene]-tetrahydro-l,3-thiazolylidene-methyl -1.3-thiazolium iodide (Scheme 5). It implies that the 4-phenyl thiazole ring having the... 

Many thiazolium salts are polarographically reducible [283, 284] 3-methylben-zothiazolium iodide [283] is reduced in a single wave a preparative reduction gave n between 1 and 2, and a mixture of dimer and monomer 2,3-dihydro-3-methylbenzothia-zole was found. Aryl groups in the 2-position hinder dimerization [283]. With TEAP as supporting electrolyte 2-methyl-3-ethylbenzothiazolium ion gives two, one-electron waves [284].
