The reaction tolerates a wide range of terminal alkynes having several synthetically useful functional groups and proceeds regioselectively to furnish hydroborated products in moderate to excellent yields. This system shows moderate chemoselectivity towards terminal C≡C bond over terminal and internal C=...

The reactions of simple phenylacetylene, meta- and ortho-methyl substituted phenylacetylene all proceeded well and afforded the corresponding aliphatic internal alkynes in good yields Discussion Since the method had been established, we then tried to gain some insights into the catalytic pathway. To ...
The curtain rises for a molybdenum alkylidyne complex that efficiently catalyzes the metathesis of internal and terminal alkynes by the breaking and making of CC triple bonds. In their Communication on page13019ff., M. Tamm etal. describe the synthesis of 2,4,6-trimethylbenzylidyne complexes ...
