Rhodium-Catalyzed Hydrosilylation of Alkenes with Acylhydrosilanes

Acylsilanes are an important class of organosilicon compounds that have gained increased attention recently. Their various reaction modes in particularly their ability to generate carbenes under thermal or photochemical conditions render them valuable reagents in organic synthesis. In this communication, an unprecedented route towards acylsilanes is reported by introducing the acylsilane moiety directly in a single step through alkene hydrosilylation. In this context, acylhydrosilanes representing a novel class of acylsilanes are introduced and applied as silylation reagents in rhodium catalyzed alkene hydrosilylations to access a great variety of acylsilanes. These reactions occur in good to excellent yields under mild conditions and show high functional group tolerance and atom economy.
