Electrosynthesis and X‐ray Crystallographic Structure of ZnIImeso‐Triaryltriphenylphosphonium Porphyrin and Structural Comparison with MgIImeso‐Triphenylphosphonium Porphine

“…of P(O)Ph 3 is initially present in the solution to be electrolyzed. The missing P(O)Ph 3 amount may be formed during the electrolysis [oxidation of PPh 3 in presence of trace amount of water leads to P(O)Ph 3 ] and/or might be produced during the work‐up (extraction of the supporting electrolyte with several aqueous washings under an air atmosphere).…”

Rates and Equilibria of the Reactions of Tertiary Phosphanes and Phosphites with Benzhydrylium Ions

“…, which then enter into fast chemical reactions with nucleophilic components of the solution. Therefore, tertiary phosphorus compounds are oxidized irreversibly and consume less than one electron per molecule 44. Figure 12 shows a good correlation of the nucleophilicities N of six tertiary phosphanes and phosphites with their half‐wave oxidation potentials E 1/2 towards the reference electrode Ag/AgNO 3 ( c = 0.01 M ) in acetonitrile.…”

Evaluation of Transition Metal Catalysts in Electrochemically Induced Aromatic Phosphonation

“…Electrochemical properties of the catalyst complexes were studied in CH 3 CN in the absence and in the presence of increasing amounts of diethyl- H -phosphonate (DEP). It was well-known that dialkyl- H -phosphonates (RO) 2 P(O)H or diaryl phosphine oxides Ph 2 P(O)H) were not oxidized in the available potential range [19,33,38,39], while their sodium salts, for example, (RO) 2 P(O)Na, were oxidized in the average potential range [54]. Similar observations were made for AgP(O)(OEt) 2 [20] and Ph 2 P(O)Ag [44] silver salts (Figure 1).…”
