Syntheses are reported for 2,3,3-trimethyl-3H-indoles and 1,1,2-trimethyl-1H-benzindoles with fluorine-containing substituents (CF3, SCF3, and SO2CF3) at C-5 and for carbocyanine, merocyanine, and styryl dye derivatives of these indoles.The fluorine-containing substituents studied produce a bathochromic effect in the styryl dyes, hypsochromic effect in the merocyanine dyes, and, as a rule, a hypsochromic effect in the carbocyanine dyes.
