The crystallographically characterized ruthenium complex RuHCl(A-Pr-PNP)(CO) (1) [A-'Pr-PNP = 4,5-bis-(diisopropylphosphinomethyl) acridine], which bears a nonplanar acridine moiety, catalyzes in a neutral medium the transformation of primary alcohols to the corresponding acetals with the liberation of H2. In the presence of base, complex 1 catalyzes the dehydrogenative coupling of alcohols to form esters. Acetal formation may involve hemiacetal dehydration to form an enol ether followed by alcohol addition to the double bond.
