Abstract
1-Benzoyl-2-phenylacetylene reacted with N-(carbamimidoyl)thiourea in glacial acetic acid saturated with 20% HBr to give (4,6-diphenyl-2H-1,3-thazin-2-ylidene)guanidine hydrobromide. The reaction of the same compounds in anhydrous ethanol in the presence of sodium ethoxide led to the formation of N-(4,6-diphenylpyrimidin-2-yl)thiourea. Bis(3-oxo-1,3-diphenylprop-1-en-1-yl) sulfide and 1-benzoyl-2-ethylsulfanyl-2-phenylethylene were isolated in the reactions of 1-benzoyl-2-phenylacetylene with N-(carbamimidoyl)thiourea and N-(carbamimidoyl)-S-ethylisothiuronium bromide, respectively, in anhydrous methanol.
