The relative rates of reaction of acetylenic acids, alcohols, esters, ethers, halides, and hydrocarbons with dicobalt octacarbonyl have been determined. The differences in the relative reactivities are not great; however, carboxy-, carbomethoxyand methylol-groups appear to enhance the reactivity when attached to the triple bonded carbon. The observed relative reactivities are not correlated with possible electronic effects. A decrease in ...
