Synthesis, characterization, and catalytic alkyne polymerization results for the first trianionic pincer alkylidyne complex, [(BuOCO)-Bu-t]W CC(CH3)(3)(THF)(2) (6), are described. Complex 6 is a highly active catalyst for the polymerization of acetylenes and exhibits a high turnover number (4371), activity (1.05 x 10(6) g(PPA) mol(cat)(-1) h(-1)), and yield (87%) for the polymerization of 1-ethynyl-4-fluorobenzene.
