โฆ Synopsis
The catalytic system Pd(OAc)Jdppb/PPhJp-TsOH catalyzes the hydroesterification of alkynes and alkynols with formate esters to give unsaturated esters in good yields and selectivities.

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
