✦ Synopsis

Arylation and alhenylation of 1-ethoxy-l-trimetylsilyloxycyclopropane with diphenyliodonium tetrafluoroborate and alkenyliodonium tetrafluoroborate were accomplished by slow addition of silyloxycyciopropane to iodonium salts in the presence of Pd( OAc) 2 (2 tool %) and DME/H20 (4 : 1) to afford ~ substituted ester. Alternatively, carbonylative coupling of silyloxypropane was carried out by slow addition of silyloxypropanes to iodonium salts under CO(I arm) at room temperature in aqueous medium, The palladium-catalyzed coupling of ketene trimethylsilyl acetals with iodonium salts is also described.
