ESCA study of transition metal complexes of secondary phosphine chalcogenides: [M2(PR3)2(μ-EPR′2)2]

Synthesis and structural characterization of platinum(II) bis(chelate) complexes derived from the ligand system meso/rac-Ph(O)HPCH2CH2PH(O)Ph

“…12.-By briefly treating a CH2C12 solution of complex 3 with dry HCl the monocationic complex 12 was rapidly produced and isolated in high yield [equation (6)]. Interestingly enough, under these conditions complex 12 does not readily undergo further protonation by HC1.…”

“…Under more acidic conditions (prolonged exposure to HC1 in CH,C12) the broad resonance at 6 119.2 shifts to 120.7 [J('95Pt-31P) 2486 Hz] and sharpens considerably. This observation suggests that in the presence of excess HCl the monocationic complex 12 is protonated to give the dicationic complex syn-[Pt{(R,S)-Ph(OH)P(CH2),P(0H)Ph),1c1, 10 [equation (6)] in which the 'syn' oxygen configuration has been retained. We have been unable to isolate complex 10 for the purpose of an X-ray diffraction study.…”

Sulfur Poisoning and Self‐Recovery of Single‐Site Rh1/Porous Organic Polymer Catalysts for Olefin Hydroformylation

“…Moreover, a new peak of P 2P 3/2 formed at 129.3 eV, which should relate to the PPh 3 poisoned by H 2 S [24] . Besides, a new peak of S 2P 3/2 emerged at 161.7 eV for Rh 1 /POPs−SR unexpectedly (Figure 4c, Table S5), which should ascribe to the coordinated sulfur species of [SH]/Rh (161.6 eV) [25] when compared with other alternative sulfur species, such as (P(C 6 H 5 ) 3 ) 2 ‐SH (162.0 eV), [26] (S=P(C 6 H 5 ) 3 ) (162.5 eV), [27] S (164.40 eV), Rh 2 S 3 (163.4 eV) and H 2 S 170.7 eV [22a] . U. Yoshio et al.…”

“…of 2P 3/2 of Rh 1 /POPsÀ SR was 130.9 eV, lower than that of the 131.3 eV in Rh 1 /POPsÀ R as well (Figure 4b, Table S5), which may be related to the strong electronegativity effect of sulfur (S, 2.58; P, 2.19; Rh, 2.28). [23] Moreover, a new peak of P 2P 3/2 formed at 129.3 eV, which should relate to the PPh 3 poisoned by H 2 S. [24] Besides, a new peak of S 2P 3/2 emerged at 161.7 eV for Rh 1 /POPsÀ SR unexpectedly (Figure 4c, Table S5), which should ascribe to the coordinated sulfur species of [SH]/Rh (161.6 eV) [25] when compared with other alternative sulfur species, such as (P(C 6 H 5 ) 3 ) 2 -SH (162.0 eV), [26] (S=P(C 6 H 5 ) 3 ) (162.5 eV), [27] S (164.40 eV), Rh 2 S 3 (163.4 eV) and H 2 S 170.7 eV. [22a] U. Yoshio et al also determined the adsorption dissociation of H 2 S as [SH] on the Rh x P catalyst during the hydrodesulfurization process.…”

Kinetically Controlled Synthesis of Metallic Glass Nanoparticles with Expanded Composition Space

“…The Pd 3d 5/2 peak at 337.0 eV is assigned to Pd─P. [ 29 ] The minor Pd 3d 5/2 peak at 338.3 eV could be assigned to be Pd─O [ 30 ] due to the surface oxidation. The Ni 2p 3/2 peak at 852.9 eV is assigned to Ni─P, and the peak at 857.0 eV is its satellite peak [ 31 ] (Figure 2h).…”
