Ethyl 2- -, ethy

When a-positions in thienothiophenes 1 and 2 are both blocked, the formyl group enters a /7-position. Thus, formylation of 5-ethyl-2-ethy lthiothieno [2,3-6] thiophene and 5-ethyl-2-ethylthiothieno[3,2-h]-thiophene afforded high yields of the 3-formyl derivatives220 [Eqs. (64) and (65)]. 2-Ethylthiobenzo[h]thiophene reacts analogously. 

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...
