Study on the anti‐sulfur‐poisoning characteristics of platinum–acetylide–phosphine complexes as catalysts for hydrosilylation reactions

A series of platinum-acetylide-phosphine complexes were synthesized and their anti-sulfur-poisoning characteristics investigated. In comparison with Speier's and Karstedt's catalysts, the platinum-acetylide-phosphine complexes exhibited both higher catalytic activity and selectivity for the -adduct for the hydrosilylation reactions under the same conditions. Furthermore, the complexes also exhibited a strong ability to resist to sulfur-poisoning. This indicated that the alkyne ligands containing the silyl group had a strong impact on the hydrosilylation reaction. Copyright (c) 2014 John Wiley & Sons, Ltd.
