The cationic ruthenium catalyst generated upon the acid–base reaction of H2Ru(CO)(PPh3)3 and 2,4,6-(2-Pr)3PhSO3H promotes the redox-triggered C–C coupling of 2-alkynes and primaryalcohols to form (Z)-homoallylic alcohols with good to complete control of olefin geometry. Deuterium labeling studies, which reveal roughly equal isotopic compositions at the allylic and distal vinylic positions, along with

In contrast to the literature, with butyllithium only one and the same dianion - namely 7 - is formed starting with each of the three hydrocarbons 1, 4, and 6. On the other hand, upon working at low temperature in tetrahydrofuran as the solvent we were able to detect the three corresponding monoanions 9, 15, and 16, most interestingly 15 and 16 at temperatures higher than -40 degrees C show rearrangement with 1,3-hydrogen shift.
