A ruthenium(II)-catalyzed highly selective Markovnikov hydrogenation of terminal epoxides to secondary alcohols is reported. Diverse substitutions on the aryl ring of styrene oxides are tolerated. Benzylic, glycidyl, and aliphatic epoxides as well as diepoxides also underwent facile hydrogenation to provide secondary alcohols with exclusive selectivity.

The present invention includes a method of treating or preventing a bacterial infection in a subject in need thereof. The method comprises administering to the subject a therapeutically effective amount of at least one compound of the invention. In certain embodiments, the bacterium is Gram-negative. In other embodiments, the bacterium is obligatory aerobic.
Compounds of the formula ##STR1## WHEREIN Ar.sub.1 and Ar.sub.2 denote an optionally substituted aromatic hydrocarbon radical or a monocyclic, monoazacyclic or diazacyclic radical of aromatic character and Alk represents lower alkylene, or salts thereof, exhibit .beta.-receptor-blocking, blood pressure-lowering and vasodilatory effects and are useful for example in the treatment of arrythmias and angina pectoris, and as blood pressure-lowering agents.
