Preparation and coordination chemistry of p-(xylylenediaminodiphenyl) phosphine

Synthesis and characterization of tris{2-(N,N-bis(diphenylphosphino) aminoethyl} amine derivatives: Application of a palladium(II) complex as a pre-catalyst in the Heck and Suzuki cross-coupling reactions

“…The 31 P-{ I H} NMR spectra 3a and 3b displayed singlets at 30.7 ppm and 16.9 ppm in DMSO, respectively. The chemical shifts of 3a and 3b are similar and within the expected range of other reported structurally similar complexes [46][47][48][49]. For Pt complexes 3b, the 31 P-195 Pt coupling constant (3400 Hz) agrees with cis ligand arrangement [50].…”

Cross‐coupling reactions in water using ionic liquid‐based palladium(II)–phosphinite complexes as outstanding catalysts

“…Typical spectra of these complexes are illustrated in the supporting information. Both of the isolated dichloropalladium(II) complexes 1a and 2a are found to have the cis configuration, characteristic of phosphinites having mutual cis arrangement . The 13 C‐{ 1 H} NMR spectra display well‐resolved signals for the phenyls and cyclohexyl carbons, respectively .…”

Synthesis and characterizations of N,N′‐bis(diphenylphosphino)‐2‐(aminomethyl)aniline derivatives: application of a palladium(II) complex as pre‐catalyst in Heck and Suzuki cross‐coupling reactions

“…For example, in the sulfurization of 1, resonance due to the starting compound 1 (39.48; 26.10 ppm) and the desired product 2b (59.94; 53.11 ppm) were observed at the beginning of the reaction. [29] This is not surprising since elemental sulfur and selenium are weaker oxidizing agents than hydrogen peroxide. After the completion of the reaction, the signal of the starting compound 1 disappeared because of the desired product 2b.…”
