The complex [Au(IPr)(2-oxazolidinone)] (1 = IKa) was prepared from reaction of [Au(IPr)Cl] (2), K₂CO₃, and propargyl amine (PPA). Kinetic studies have been performed for acid cleavage of 1 to yield the oxazolidinone product and an [Au(IPr)(X)] adduct. The fastest rates of cleavage were found to occur for the hydrogen chloride salt of PPA (PPA-HCl) and for the CO₂ adduct of PPA, PPA-CO₂ = the carbamic acid (CA). This transformation was studied as a function of [CA], pressure of CO₂ as well as temperature. Detailed computational studies support the formation of a key intermediate and are also in agreement with a rapid carbonylation/decarbonylation reaction. The computed reactions mechanisms for addition of PPA-HCl and CA are also presented as well as the crystal structure of 1.

 由[Au（IPr）Cl]（2），K ₂ CO ₃和炔丙基胺（PPA）的反应制备[Au（IPr）（2-恶唑烷酮）]络合物（1＝ IKa ）。进行了1酸裂解的动力学研究，得到了恶唑烷酮产物和[Au（IPr）（X）]加合物。发现最快的裂解速率发生在PPA的氯化氢盐（PPA-HCl）和PPA的CO ₂加合物中，PPA-CO ₂  =氨基甲酸（CA）。研究了这种转变与[CA]，CO ₂压力的关系。以及温度。详细的计算研究支持关键中间体的形成，并且也与快速的羰基化/脱羰基反应一致。还介绍了计算的添加PPA-HCl和CA的反应机理，以及1的晶体结构。
