We have shown that reaction of a triphasic system of metallic selenium-aqueous-phenylacetylene at 80-120~ in the presence of a phase transfer catalyst leads to the formation of Z-2-benzylidene-4-phenyl-l,3-diselenole (I) in -20% yield (based on the selenium taken). Ph.
Oxidation of the title compounds, in contrast to that of ''normal'' (Z,Z)-buta-1,3-diene-1,4-dithiolates, does not lead to the formation of 1,2-dithiins. Thus, the aliphatic diaminodithiolates 7 and 8 were converted into the (E)-2-butenedithioamides 12 and 15 as a result of resonance stabilization o
