## Abstract A highly efficient hydroesterification of alkynes employing aryl formates has been developed without the use of external carbon monoxide and at ambient pressure. The reaction in the presence of a palladiumโ€xantphos catalyst system selectively affords ฮฑ,ฮฒโ€unsaturated esters in good to hi

Palladium(II) regioselectively catalyzes the hydroesterification of terminal alkynes under syngas forming a,b-unsaturated esters 3 and 4 in excellent chemical yields under neutral conditions. The high selectivity for the linear ester 4 was obtained with a catalytic system that includes Pd(II), 1,4-b
