H, Me) in trifluoroacetic acid solution exhibit two-component equilibrium mixtures 89A 89B (92KGS1689). For 4-methyl derivatives (R4 = Me), two fixed conformers (C(2)--NHR4 bond rotamers) of the cyclic tautomer 89B (E and Z) were detected. The equilibrium 89A 89B is rather insensitive to the nature of the substituent X (R2 = XC6H4). On passing from the aromatic aldehyde to the acetophenone derivatives, the equilibrium amount of the cyclic tautomer 89B increases. The cyclic protonated form of 2-chloro-6-nitrobenzaldehyde thiosemicarbazone could not be detected at all. It would be of interest to test the thiosemicarbazones of other 2,6-disubstituted benzaldehydes. Recently, it has been found (94KGS119) that the protonated cinnamic aldehyde thiosemicarbazone 89A (R1 = PhCH = CH, R2 = R3 = R4 = H) likewise does not form the cyclic tautomer 89B in trifluoroacetic acid solution. [Pg.52]
