BENZENOID-QUINONOID TAUTOMERISM IN AZOMETHINES AND THEIR STRUCTURAL ANALOGS. XLVIII. TAUTOMERISM AND PHOTOCHROMISM OF 2-(2-HYDROXYPHENYLAMINOMETHYLENE)-3(2H)-BENZOTHIOPHENONE AND ITS ACETYL DERIVATIVES

2-(2-Hydroxyphenylaminomethylene)-3(2H)-benzothiophenone and its diacetyl derivatives were synthesized.In solution of the monoacetyl derivative there is a tautomeric transformation in which mutual exchange by the acetyl group and a proton occurs between the N- and O'-centers, and in polar solvents (DMSO, DMFA, HMPTA) a tautomeric equilibrium is established.Two photochromic processes are observed in solutions of the diacetyl derivative under the influence of light: (E), (Z) isomerization of 2-(2-acetoxyphenylaminoethylene)-3(2H)-benzothiophenone and N -> O photoinitiated acylotropic rearrangement od 2-(N-acetyl-2-hydroxyphenylaminomethylene)-3(2H)-benzothiophenone
