Regioselective incorporation of CO into enamines by rhodium-catalyzed reaction with a hydrosilane and CO
摘要:
In the presence of [RhCl(CO)2]2, the reaction of enamines with a hydrosilane and carbon monoxide (140-degrees-C, 50 atm of CO) resulted in regioselective incorporation of CO into the alpha-carbon atom to give alpha-(siloxymethylene) amines, which can be easily converted into alpha-siloxy ketones by hydrolysis.
