Carbonylation of terminal alkynes catalysed by Pd complexes in combination with tri(2-furyl) phosphine and methanesulfonic acid
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 degrees C and P(CO)= 20 bar) with high regioselectivity (ca. 95%) towards the formation of 2-substituted acrylic ester.
