Pd(OAc)2 in combination with tri(2-furyl)phosphine and methanesulfonic acid is an efficient catalyst for the alkoxycarbonylation of 1-alkynes. Fairly good reaction rates are obtained under mild conditions (50-80°C and P(CO) = 20 bar) with high regioselectivity (ca. 95%) towards the formation of 2-substituted acrylic ester.

Abstract
Pd(OAc)2 in combination with tri(2-furyl)phosphine and methanesulfonic acid is an efficient catalyst for the alkoxycarbonylation of 1-alkynes. Fairly good reaction rates are obtained under mild conditions (50-80°C and P(CO) = 20 bar) with high regioselectivity (ca. 95%) towards the formation of 2-substituted acrylic ester.
