Abstract
In the presence of methanesulfonic acid, the palladium(0)-olefin complexes:
[Pd(eta (2)-ol)(P-N)] [ol = dimethyl fumarate or fumaronitrile, P-N = 1-(P
h2P)C6H4-2-CH=NR (R = CMe3 or C6H4OMe-4)] catalyse the alkoxycarbonylation
of terminal alkynes. Moderately good rates are obtained when the catalysts
are promoted with two equivalents of the free P-N Ligand and a large excess
of acid at 120 degreesC. The catalytic data suggest that derivatives of th
e type [Pd(alkyne)(P-N)(n)] (n = 2-3) are the active catalytic species. (C)
