Abstract

This study presents a method for synthesizing β-(E)-vinylsilanes through the hydrosilylation of terminal alkynes with diverse secondary silanes, employing platinum(II) complexes with P,N-donor ligands. The method achieves selective hydrosilylation under solvent-free conditions, yielding up to 99% of alkenylhydrosilanes. It accommodates a wide range of aliphatic, aromatic, and heterocyclic alkynes, representing an advancement in platinum-based protocols by promoting mono-hydrosilylation with secondary silanes. The versatility of this approach is further demonstrated by subsequent transformations of β-(E)-vinylsilanes, indicating its broad applicability in organic synthesis and material chemistry.

期刊介绍： The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes. The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods. The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
