富电子的κ2键三（吡唑基）硼酸盐配体稳定了金(I)的乙烯配合物。较大的烯烃碳核磁共振上移和相对较长的金结合乙烯的CC距离表明，相对于弱供体配体支持的类似物，Au(I)→乙烯π背成键显著，与计算数据一致。
Ethylene complexes of gold(I) have been stabilized by electron-rich, κ2-bound tris(pyrazolyl)borate ligands. Large up-field shifts of olefinic carbon NMR resonances and relatively long CC distances of gold bound ethylene are indicative of significant Au(I) → ethylene π-backbonding relative to the analog supported by a weakly donating ligand, consistent with the computational data.
