DOI: 10.1039/c8ra04083d
Abstract: In this study, ruthenium(II)-catalyzed direct hydrosilylation of internal alkynes with high regio-selectivity and stereo-selectivity is reported. This title transformation led to various vinylsilanes in good to excellent yields. This approach features mild reaction conditions, low… read more here.
