  释放阴离子：评估弱配位阳离子

  摘要：

  研究了一系列常用的弱配位阳离子 (WCC)，包括四烷基铵、双（三苯基膦）亚胺 (PPN)、P2 和 P5 磷氮鎓以及四苯基磷离子以及另外五个四芳基磷离子 [Ar = 4-Me, 4- t - Bu、3,5-Me 2、4-Me 2 N和3,5-(MeO) 2苯基衍生物]。在气相和二氯甲烷中计算了它们的氯化物络合物的离解焓。将这些结果与氯仿中这些盐的红外光谱进行了比较 - d提供自由和结合的 C-D 延伸，19相应四氟硼酸盐的 F NMR 光谱、离子对平衡常数以及氯化物和乙酸盐与 1-碘辛烷的反应速率。后者的转化也在催化条件下进行。发现取代的四苯基膦离子衍生物是非常好的 WCC，其功能与 P2 和 P5 磷氮鎓离子（目前的 WCC 金标准）一样好或更好。

  Tetraphenylphosphonium carboxylates and sulfonates. Synthesis and structure

  摘要：

  The reaction of the pentaphenyphosphorus solvate Ph5P center dot 1/2PhH (I) with carboxylic and sulfonic acids was used to synthesize tetraphenylphosphonium carboxylates Ph4POC(O)R, R = C6H4(2-OH) (II), C6H4 (2-COOH) (III), H (IV), Me (V), CCl3 (VI), Ph (VII), PhCH=CH (VIII), CH2CH2C(O)OH (IX), CH=CHC(O) OH(X), and CH2C(O)OH (XI) and tetraphenylphosphonium sulfonates Ph4POSO2Ar, Ar = Ph (XII), C6H4Me4 (XIII), and C6H3(-COOH)(4-OH) (XIV). Compound XII was also prepared from compound I and SO3 in benzene. According to X-ray diffraction data, the crystals of I contain two types of crystallographically independent molecules with a slightly distorted trigonal-bipyramidal configuration [Ia, CaxPCax 178.44(8)A degrees, P- C-ax 1.985(2), 1.987(2) A..., P-C-eq 1.854(2), 1.846(2), 1.840(2) A...; Ib, CaxPCax 178.45(9)A degrees, P-C-ax 1.980(2), 1.975 (2) A..., P-C-eq 1.840(2), 1.846(2), 1.854(2) A...]. In the cations of compounds II, III and XIV, the coordination of the phosphorus atom is tetrahedral [CPC angle: II, 106.2(2)-111.6(1)A degrees; III, 104.01(6)-113.03(6)A degrees; XIV, 107.54 (6)-112.79(6)A degrees]; the anions contain intramolecular O-Ha <-O hydrogen bonds between the hydroxyl hydrogen atom and carboxyl oxygen atom (II, 1.34; III, 1.23; and XIV, 1.83 A...).
