A series of platinum–acetylide–phosphinecomplexes were synthesized and their anti‐sulfur‐poisoningcharacteristics investigated. In comparison with Speier's and Karstedt's catalysts, the platinum–acetylide–phosphinecomplexes exhibited both higher catalytic activity and selectivity for the β‐adduct for the hydrosilylationreactions under the same conditions. Furthermore, the complexes also exhibited

Ligand exchange of cis-bis(diphenylphosphino)ethylene (dppee) with trans-(Ph3P)2Pt(CCR)2 easily generates the cis-complexes (dppee)Pt(CCR)2 in 64–95% yield. This transformation is used to convert pyridine-containing macrocycle 7 to its cis-analogue 8 and the macrocyclic bipyridine analogue 10 to the unique macrocyclic ligand 11. X-ray structural characterization of trans-complexes 5a and 5b and cis-complexes
