Half-sandwich ruthenium(II) complexes of aminophosphines: synthesis, structures and catalytic applications in C–C coupling reactions between styrenes and diphenyldiazomethane

“…Solvents were dried and distilled under the nitrogen atmosphere prior to use. The aminophosphines, RN(H)PPh 2 (R 0/ Ph, [25] C 6 H 11 [17i]), bis(diphenylphosphino)amines, RN(PPh 2 ) 2 (R 0/Et, n Pr, i Pr [26], n Bu [27]), CpRuCl(PPh 3 ) 2 [28] and Ph 2 CN 2 [29] were prepared according to the literature procedures, whereas styrene, a-methyl styrene and 4-methyl styrene were purchased from Aldrich and used without further purification. NMR spectra were recorded using VXR 300 and Bruker AMX 400 spectrometer and shifts were determined with reference to deuterium signal of the solvent employed.…”

Synthesis and structural characterization of the mono- and diphosphine-containing diiron propanedithiolate complexes related to [FeFe]-hydrogenases. Biomimetic H2 evolution catalyzed by (μ-PDT)Fe2(CO)4[(Ph2P)2N(n-Pr)]

“…Calc. for C 24 To a stirred red solution of parent complex A (0.386 g, 1.0 mmol) in MeCN (25 mL) was added Me 3 NO Á 2H 2 O (0.111 g, 1.0 mmol). After the mixture was stirred at room temperature for 10 min, Ph 2 PH (0.190 g, 1.0 mmol) was added, and the new mixture was stirred for 1 h. The same workup as that for the preparation of 1 using CH 2 …”

“…Me 3 NOÁ2H 2 O, n-BuLi (2.5 M in hexane) and Ph 2 PC 2 H 4 PPh 2 were commercially available and used as received. (l-PDT)Fe 2 (CO) 6 (A) [20], Ph 2 PH [21], CpFe(CO) 2 I [22], Ph 2 PNH(t-Bu) [23] and (Ph 2 P) 2 NR(R = n-Pr,n-Bu) [24,25] were prepared according to literature methods. Preparative TLC was carried out on glass plates (26 Â 20 Â 0.25 cm) coated with silica gel G (10-40 lm).…”

Synthesis and characterization of [MCl2( n Pr-N(Ph2P)2] (M = Pt, Pd) complexes and hydroformylation of 1-octene using [PtCl2(R-N(Ph2P)2)] (R = benzyl, 2-picolyl, n Pr) complexes

“…The aminodiphosphine ligands 1 and 2 were prepared according to the reported literature procedures [15,16]. The platinum(II) and palladium(II) complexes (3)(4)(5) were prepared following straightforward synthetic routes, by the reaction of the ligands 1 and 2 with either PtCl 2 (cod) or PdCl 2 (cod) in CH 2 Cl 2 (Scheme 1).…”
