Pyrano- and pyrylium mono-8[4(1)] and/or 5(6)-[2(4)]methine cyanine dyes (6a-k, 7a-f) were synthesized based on acyclic heterocyclic Schiff bases of pyrolo[3,2-d]pyrazole[oxazole(imidazol-6-one)]-1-ium iodide salts, 5-acetyl-N-aryl[pyrazolinyl(pyridinyl)]pyrolo-[5,4-d]pyrazolin-iodide salts, and/or (anhydro bases) precursors (1a-i, 2a-I, 3a-i, 4a-i, and 5A,Ba-i). The structure of pyrylium-9-chloride and/or iodide and their pyrano(pyrylium)-mono-8[4(1)] and 5(6)[2(4)]methine cyanine dyes was identified by elemental and spectral data. The absorption spectra of some selected dyes were investigated in 95% EtOH, polar (nonpolar) organic solvents and in universal buffer solutions to investigate the optimal conditions for the application of such dyes as photosensitizers.

The reaction of a ratio of 1 mol of 5-chloro-3-methyl-1-phenylpyrazolo-4-[2(4)-ethylpyridinium]dimethine cyanine or 5-chloro-4-formyl-3-methyl-1-phenylpyrazole(I) with 2 mol of an appropriate 2(4)-heterocyclic quaternary salt afforded novel pentamethine cyanine dyes. Other reactions of I with heterocyclic nitrogen bases, followed by condensation of the quaternary nitrogen salts with methylheterocyclic iodide salts provided the corresponding unsym. dimethine cyanine dyes. The new pentamethine and dimethine cyanine dyes were identified by elemental analyses and IR and ¹H-NMR spectral data. The visible absorption spectra of some selected dyes were investigated in pure and mixed solvents as well as in universal buffer solutions The measure of the variation of absorbance with pH was utilized for the determination of the pK_a values, and these data are discussed.

The transformation of a single C-F bond of trifluoromethylarenes bearing a hydrosilyl group at the ortho position was achieved. The activation of the hydrosilyl group with a trityl cation in the presence of nucleophiles allowed for selective C-F bond functionalization, for example, by allylation, carboxylation, or chlorination. Further derivatization of the resulting fluorosilylarenes afforded various aromatic difluoromethylene compounds
