Synthesis of acylsilanes via silastannation of alkynes by a palladium-isocyanide catalyst
摘要:
Silastannation of 1-alkoxyalkynes was carried out at room temperature by use of a palladium acetate/tert-alkyl isocyanide catalyst, to produce 1-alkoxy-1-silyl-2-stannylalkenes. Palladium-mediated coupling of the organotin moieties with organic halides followed by acid-catalyzed hydrolysis provided a variety of acylsilanes.
