摘要

The reaction can be illustrated by the formation of isopropyl 3-phenylpropionate (Za, R= i- Pro, 50%) in the reaction of 1-isopropoxy-1-trimethylsiloxycyclopropane (la)* with phenyl triflate (1 equiv, 100" C, benzene or butyonitrile) in the presence of 5-10 mol% of a palladium catalyst. 11a Interestingly, palladiumcatalyzed arylation of la with PhN2BF,, which is known to generate in situ a cationic arylpalladium species upon reaction with a palladium catalyst ...
