Platinum (0) alkyne complexes and a method for their preparation.

摘要

A simplified method of manufacture for platinum (O) alkyne complexes is disclosed, as well as novel platinum (0) alkyne complexes per se. The complexes are made by reacting platinum-vinylsiloxane complexes with alkynes. The complexes are used in hydrosilylation, hydrogenation, isomerization and oligomerization reactions. Curable silicones using these platinum (0) alkyne complexes as curing catalysts are also disclosed.
