Imidazolidinethione (II) reacts with benzoylphenylacetylene (Ia) to give a mixture of (E,Z)-3,3'-thiodi(1,3-diphenylprop-2-en-1-one) (IVa) and its (Z,Z)-isomer (Va) in a ratio of about 3:1.However, p-anisoyl-(Ib)- and p-chlorobenzoyl-(Ic)-phenylacetylenes give only the corresponding (E,Z)-isomers (IVb and IVc).On the other hand, ammonium phenyldithiocarbamate (III) reacts with Ib and Ic to give (Z,Z)-3,3'-thiodi(1-p-methoxyphenyl-3-phenylprop-2-en-1-one) (Vb) and (Z,Z)-3,3'-thiodi(1-p-chlorophenyl-3-phenylprop-2-en-1one) (Vc) and its (E,Z)-isomer (IVc), respectively.Isothiocyanic acid reacts with aroylphenylacetylenes (Ia-c) to give the corresponding 1-aryl-3-isothiocyano-3-phenylprop-2-en-1-ones (VIa-c) which fail to react with ammonia and aliphatic amines.
