资源简介：
A bis(tri-n-butylphosphine)palladium ((nBu3P)2Pd) complex was shown to catalyze the cyclization of arylallenes with carbon dioxide to yield six-membered lactones. The stoichiometric reaction of a (Me3P)2Pd complex with 1 equiv of arylallenes, followed by treatment with CO2, resulted in the formation of five-membered palladalactones, the structures of which were fully characterized by X-ray crystallography, NMR, IR, HRMS, and elemental analysis.
