Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Various new substituted naphthopyrane compounds were synthesized through a one-pot condensation of substituted benzaldehydes with beta-naphthol and 1, 3-dione compounds in the presence of Cu(OTf)2 using ultrasonic irradiation and conventional heating. The structures of the obtained new compounds have been clarified by spectroscopic methods (FTIR, 1H NMR, 13C NMR, and GC-MS) after the purification processes. 80 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The book deals with the synthetic and spectral studies of substituted 2-aminobenzenethiols and their conversion into phenothiazines, 4H-1, 4-benzothiazines and 1, 4- benzothiazino- (2,3-b)-phenothiazines. It also includes the oxidation behavior of 4H-1, 4-benzothiazines and the synthetic and spectral studies of substituted (1,4)- benzoxazino (2,3-b)-phenoxazines. Synthesis of 2-amino-3-methyl-5-nitrobenzenthiol by alkaline hydrolysis of 2-amino-4-methyl-6-nitrobenzothiazole. Synthesis of phenothiazines. by smiles rearrangement of substituted 2-formanido-2-nitrodiphenyl sulphides. The latter were obtained by the reaction of substituted 2-aminobenzenethiol with o-halonitrobenzenes and followed by formylation. Synthesis of 4H-1,4-benzothiazines by the condensation and oxidative cyclisation of 2-aminobenzenethiols with beta-diketone in DMSO. Substituted 1,2,4-trithenodithiazin-3-ones prepared by condensing substituted o-aminobenzenethiols with halogeno-p-benzoquinones (chloranil/bromanil) in presence of fused sodium acetate These were further condensed with some of different o-aminothiophenols yielding 1,4-benezothiazino-(2,3-b)-phenothiazins derivatives. 236 pp. Englisch.
