Abstract

3-hexyne to give colorless W (~ S-CSEt5)(Ot-Bu) Oz18 and tetramethylethylene quantitatively, possibly via intermediate, unstable W (qS-CSEt5)(0CMe2CMe20)(0-t-Bu). I9 The question that remained was why alkyne metathesis using W (CR)(Ot-Bu), catalysts eventually ceases? We know that W2 (0-t-Bu), cannot be formed since it reacts with dialkylacetylenes to give W (CR)(Of-Bu) J. 21 A simpler'active" system consisting of a ...
