Hazard Predictions

• Potentially hazardous: May be hazardous but unknown

Species of the type Ni[S2C2Ar2]2 have been prepared by reactions of nickel sulfides with diphenylacetylene. More modern versions of this method entail the reaction of electrophilic acetylenes such as dimethyl acetylenedicarboxylate with well defined polysulfido complexes (Personal communication with chemical industry experts). Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility.
