Ammonium and potassium salts featuring the chiral mer-[P(C6H4CO2)3]−, mer-[1]−, have been isolated. Specifically, treating phosphorane P(C6H4CO2)2(C6H4CO2H), 2, with N-containing bases [Nbase = PhNMe2, PhNH2, pyridine (py), isoquinoline, (−)-brucine, N(n-C8H17)3] afforded ammonium salts [NbaseH]+-mer-[1]−. Each compound was fully characterized spectroscopically, and four were subjected to X-ray crystallographic
铵和钾盐为特色的手性聚体- [P(C 6 H ^ 4 CO 2)3 ] - ,聚体- [ 1 ] - ,已被分离。具体而言,处理膦P(C 6 H ^ 4 CO 2)2(C 6 H ^ 4 CO 2 2H),2,用含N的碱[N基座= PhNMe 2,PhNH 2,吡啶(PY),异喹啉,( - )-亮氨酸,N(n -C 8 H 17)3 ],得到铵盐[N基H] + -聚体- [ 1 ] - 。每种化合物在光谱上都得到了充分表征,并对四个化合物进行了X射线晶体学分析。盐与的外消旋混合物中分离聚体[ - 1 ] -阴离子除外的情况下[( - ) - brucineH]-Λ-聚体- [ 1 ],为此分析了该晶体为对映体纯。通过用KH处理2合成钾盐K- mer- [ 1 ] 。K- mer- [的固态结构1 ]是由七和八配位的K +离子组成的配位聚合物,它们被外消旋阴离子或甲醇溶剂的氧弱结合。还获得了布朗斯台德酸H(DMF)n
