Directed ortho lithiation of diphenylphosphinic acid and subsequent electrophilic trapping provides mono ortho-functionalized derivatives including enantiopure γ-aminophosphinic acids in moderate yields. Copper catalyzed coupling of the ortho anion leads to biphenyl-2,2′-diylbis(phenylphosphinic acid), a phosphorus analogue of biphenyl-2,2′-dicarboxylic acid. Preliminary studies of the metal-binding
二苯基次膦酸的直接邻位锂化和随后的亲电捕集以中等收率提供了单邻位官能化的衍生物,包括对映体纯的γ-氨基次膦酸。铜催化的原阴离子的偶联产生联苯-2,2'-二基双(苯基次膦酸),一种联苯-2,2'-二羧酸的磷类似物。包括对该O,O-螯合配体对一系列金属阳离子的金属结合能力的初步研究。
