Arsine and carbene gold(I) complexes with architectures closely related to those of 2-(di-tert-butylphosphino)biphenyl gold(I) complexes have been prepared and structurally characterized. As predicted, 2-(di-tert-butylarsine)biphenyl gold(I) complexes are more electrophilic catalysts in comparison to their phosphine analogues, whereas those based on 4-arylindazole behave similarly to NHC-gold(I) catalysts.

JohnPhos Gold（I）催化剂的主题变化：具有类似结构的Ar和碳烯配合物

已经制备并构造了结构与2-（二叔丁基膦基）联苯金（I）配合物密切相关的构型的和卡宾金（I）配合物。如所预测的，与它们的膦类似物相比，2-（二叔丁基ar）联苯金（I）络合物是更亲电的催化剂，而基于4-芳基吲唑的那些则与NHC-金（I）催化剂表现相似。
