The readily available cyclobutadiene platinum complex [(C4Et4)PtCl2] catalyzes hydrosilylation of alkenes and alkynes. The reaction typically proceeds at room temperature and does not require any solvent. The target products are obtained from both terminal and internal alkynes, as well as from terminal alkenes in 43–99% yields. The scope of silanes includes various tertiary silanes (Et3SiH, (EtO)3SiH

日期:2012.3
A variety of aromatic and alkyl acidchlorides can be selectively converted into aldehydes using dimethylphenyl silane (HSiMe2Ph) as the reducing reagent in the presence of the cationic ruthenium catalyst Cp[(i‐Pr)3P]Ru(NCMe)2}+ [PF6]−. The reactions proceed under very mild conditions and are tolerant to many functional groups.
Metal‐Free Allylic C−H Amination of Vinylsilanes and Vinylboronates using Silicon or Boron as a Regioselectivity Switch

日期:2022.11.7
A metal-free allylic C−H amination protocol allows simple vinylsilanes and vinylboronates to be selectively functionalized without competitive consumption of the reactive vinylmetalloid core structure, preserving its reactivity for future transformations such as cross-coupling or addition reactions. The silicon/boron group directs the regioselectivity of amination to the distal side of the C=C bond
