Square-planar complexes [PdCl{κ 2 -(RN = CHC 6 H 4 PPh 2 )RЈ}] (RЈ = Cl; R = 4-CH 3 C 6 H 4 , 1a; R = 2-CH 3 OC 6 H 4 , 1b; R = 2-HOC 6 H 4 , 1c; RЈ = CH 3 ; R = 4-CH 3 C 6 H 4 , 2a; R = 2-CH 3 OC 6 H 4 , 2b; R = 2-HOC 6 H 4 , 2c) have been prepared and characterized. In complexes 2a-c only formation of one isomer was observed. The Pd-methyl bond arranges in a cis position to the phosphane fragment of the P,N chelating ligand. Reaction of complexes 2a-c in acetonitrile with AgBF 4 led to removal of the chlorido ligand and coordination of acetonitrile

“…[7] Unless otherwise stated, all reactions were carried out under oxygen-free nitrogen using standard Schlenk techniques. Diethyl ether and THF were purified by reflux in the presence of sodium/benzo- [8] [{Pd(µ-Cl)(η 3 -C 3 H 5 )} 2 ], [9] [Cu-(MeCN) 4 ][PF 6 ], [10] [AuCl(tht)] (tht = tetrahydrothiophene), [11] [MCl 2 (cod)] (M = Pt or Pd), [12,13] [{RuCl(µ-Cl)(η 6 -p-MeC 6 H 4 -iPr) 2 }], [14] [{Rh(µ-Cl)(cod)} 2 ], [15] [{MCl(µ-Cl)(η 5 -C 5 Me 5 )} 2 ] (M = Rh or Ir), [16] [{PtCl(µ-Cl)(PMe 2 Ph)} 2 ], [17] [{PtCl(µ-Cl)(PMe 2 -Ph)} 2 ] [18] and [{Pd(µ-Cl)(C 10 H 8 N)} 2 ] [19] were prepared according to literature procedures. Chlorodiphenylphosphane and allylamine were distilled prior to use.…”

Reaction of allylamine with 1 equiv. of Ph2PCl in the presence of NEt3, proceeds in THF to give (allylamino)phosphane 1. 1 has been coordinated as a monodentate P ligand with Au, Pd, Pt, Ru, Rh, Ir and as a bidentate P,allyl ligand to Pt. Reaction of KOtBu with [PtCl2{Ph2PNH(C3H5)}2] in methanol gives [Pt{Ph2PNH(C3H8O)}2]. The X‐ray structures of 1.Se and four demonstrative monodentate complexes all reveal intramolecular N–H···Cl hydrogen bonding. The structure of [Pt{Ph2PNH(C3H8O)}2] consists of an N–H···O hydrogen‐bonded dimer in the solid state. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

“…Pd(cod)Cl 2 (0.23 g, 0.80 mmol, 1 eq) [28] was added to a solution of (S)-BINAP (0.50 g, 0.80 mmol, 1 eq) in CH 2 Cl 2 (5 ml) under a flow of argon. The mixture was stirred over night and then concentrated under reduced pressure to give a yellow crude material, which was washed with hexanes and Et 2 O to remove the organic byproduct.…”

Conformational flexibility of palladium BINAP complexes explored by X-ray analyses and DFT studies

et al. 2013

Several crystal structures and a theoretical DFT structure of the important catalyst (BI-NAP)PdCl2 (BINAP: 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) have been determined. The conformational flexibilities of the BINAP backbone and of the phenyl rings do not seem to be coupled. Two novel parameter have been introduced that define the Pi-Pi stacking between the phenyl and biaryl rings in systems similar to the BINAP ligand, as well as the delta angle that is sensitive to the important interaction of the exchangeable ligands of the palladium with the equatorial phenyl rings of the BINAP. Furthermore, the calculated bite angle is 3 degrees larger than the experimentally determined bite angles. (C)
