  摘要：

  The acylation of ortho-substituted (R = OH, OMe, NHTs) 2-arylaminomethylene-2,3-dihydrobenzo[b]thiophen-3-ones with (4-methyl-2-oxobenzo[b]pyran-7-yloxy)acetyl chloride results in formation of the corresponding N-acyl enaminoketones. The same reaction with 2-(2-hydroxyphenylaminomethylene)-2,3-dihydrobenzo[b]thiophen-3-one gives rise to a tautomeric mixture of acyloxyphenyl and N-acyl enamino-ketone isomers. Irradiation at a wavelength corresponding to the absorption region of the N-acyl enamino-ketone isomer leads to NCO acyl group transfer to afford O-acylated isomer. The complex formation ability of all tautomeric forms with respect to Zn2+ and Ni2+ cations and their fluorescence properties were studied.
