Synthesis of ethynyl-substituted precursors to carbon-nitrogen-sulfur extended structures: Reactions of C3N3F3 and C2N2SCl2 with alkali-metal (trimethylsilyl) acetylides

The reaction of 2,4,6-trifluoro-1,3,5-triazine with lithium 2-(trimethylsilyl)acetylide affords 2,4,6-tris(trimethylsilyl)ethynyl-1,3,5-triazine, a potential precursor to highly cross-linked carbon-nitrogen materials. The reaction of lithium and sodium 2-(trimethylsilyl)acetylide with 3,4-dichloro-1,2,5-thiadiazole results in ring opening and produces bis(2-(trimethylsilyl)ethynyl) sulfur and cyanogen as the major products. The anticipated 3,4-bis(2-(trimethylsilyl)ethynyl)-1,2,5-thiadiazole was obtained as only a minor product.
