Popis:	The catalytic activation of pro-2-ynylic ethers HCCCR 2 OMe towards carboxylic acids is controlled to regioselectively afford the functional enol esters R 1 CO 2 C(CH 2 )CR 2 OMe or R 1 CO 2 CHCHCR 2 OMe corresponding to the addition of the carboxylate to either C(2) or C(1) of the terminal triple bond, depending on the nature of the ruthenium catalyst precursor RuCl 2 (PPh 3 )( p -cymene) or Ru( η 3 -2-methylpropenyl) 2 (dppe), respectively.
