Synthesis, Properties, and Reactions of Monosulfonated Triphenylphosphine (PPh2(m-C6H4SO3K) = TPPMS) Complexes of Iridium(I). Crystal and Molecular Structure of [N(CH2C6H5)(C2H5)3+][PPh2(m-C6H4SO3)-]·H2O

“…The mean P−C distance is 1.826 Å, and the mean C−P−C angle is 102.5°; these results are insignificantly different from the values of 1.828 ± 0.005 Å and 103.0 ± 0.8° reported by Daly for the structure of PPh 3 . The geometry around phosphorus in P( p -C 6 H 4 SO 3 K) 3 ·KCl·0.5H 2 O is also nearly identical with that in PPh 3 . The sulfur atom associated with the SO 3 - group has a tetrahedral environment, with the O−S−C angles averaging 105.5° and the O−S−O angles averaging 113.1°.…”

Synthesis of Hydrophilic Phosphorus Ligands and Their Application in Aqueous‐Phase Metal‐Catalyzed Reactions

“…This might account for the lower quantity of such ligands even though the water‐solubilizing ability of carboxylates and phosphonates is comparable to sulfonate groups (Scheme 17). [46–49] …”

Water-soluble complexes MX2L2 (M = Pd, Pt; L = PPh2(C6H4-p-SO3K)): Synthesis, stereoisomerism, and catalytic activities for aromatic cyanation in n-heptane/water biphasic solution

“…In contrast, the para-substituted monosulfonated triphenylphosphine (pTPPMS) has attracted little attention as a supporting ligand in transition metal complexes. The para-isomer (pTPPMS), however, provides several advantages over the meta-isomer (mTPPMS), involving enhanced crystallinity of the ligand and its metal complexes, uncomplicated spectroscopic characteristics, and ease of preparation along with purification [21,22].…”
