from the precursor complex, [(PPh3)2Ru(CH3CN)3Cl][BPh4]. The complex has been structurally characterized. This complex has been found to be an efficient catalyst for the anti-Markovnikov addition of carboxylic acids to alkynes.

alkynes was catalyzed by mononuclear ruthenium(0) complexes to give enol esters in high yields. By using ligands with different electronic properties, product selectivity was achieved. E-enol esters were preferentially produced when tricarbonyl(η 4 -diene)ruthenium complexes were used; while geminal enol esters were produced when tricarbonylbis(phosphane)-ruthenium complexes were used.

Two Ru(II)-catalytic systems were developed for anti-Markovnikov regioselective hydroacyloxylations of terminal alkynes to vinylic esters. [Ru(NCCH3)6][(BF4)2] favors (E)-vinylic ester products with arylacetylenes and select carboxylic acids, whereas a Ru scorpionate complex with two electron-withdrawing ligands favors (Z)-vinylic ester isomers.
