The hydrogenation of benzene and other arenes under aqueous-organic biphasic conditions is evaluated using the ruthenium complexes Ru(eta(6)-C10H14)(pta)Cl-2 (pta=1,3,5-triaza-7-phosphaadamantane), Ru(eta(6)-C10H14)(tppts)Cl-2 (tppts=tris-3-sulfonatophenyl ...
The key step in the trans-selective modification of the Wittig reaction is the a-lithiation of the lithium bromide coordinated ylide-aldehyde adduct (the so-called "P-betaine"). The olefination reactions were carried out for RCHO and [R1CH2PPh3]Br (R = C ...
In aqueous solutions, RuCl2(TPPMS)(2) (TPPMS = 3-sulfonatophenyldiphenylphosphine) catalyzes the exchange between H-2 and D2O or between D-4 and H2O with high efficiency (up to 1 252 turnovers per hour) under mild conditions (298 K, 2 MPa H-2). The ex ...
The facile synthesis of five reagents (Cs+ and Ph3C+ salts) to introduce weakly coordinating anions (WCAs) Al(ORF)4- (ORF: OC(H)(CF3)2; OC(CF3)3) or lithium bridged {(RFO)2Al(m-ORF)2(m-Li)(m-ORF)2Al(ORF)2}- (Ph3C+ salt, ORF: OC(H)(CF3)2) is presented. All ...
After treatment with an appropriate base (butyllithium or sodium amide), 2-alkenyltris(2-methoxymethoxyphenyl)phosphonium salts carrying an allyl, crotyl, or prenyl (3-methyl-2-butenyl) side chain condense with satd. or unsatd. aldehydes to give conjugated ...
PX4+[Al(OR)4]- (X = I: 1a, X = Br: 1b) was prepd. from X2, PX3, and Ag[Al(OR)4] [R = C(CF3)3] in CH2Cl2 at -30 Deg in 69-86% yield. P2X5+ salts were prepd. from 2PX3 and Ag[Al(OR)4] in CH2Cl2 at -30 Deg yielding almost quant. P2X5+[Al(OR)4]- (X = I: 3a, X ...
The reaction of the cluster complexes [Pt-3(mu -CO)(3)(PR3)(3)] (PR3 = PPh3 1, PPh(2)Bz 2, PCy3 3 and P(i)pr(3) 4) with dialkyl acetylenedicarboxylate, R'O2CC drop CCO2R' (R= CH3 or Bu-t) have been examined under various conditions. At low temperature the ...
The reactions of the cluster complexes [Pt-3(mu -Co)(3)L-3], where L = PPh3 1a, PPh(2)Bz 1b and PCy3 1c, with activated mono-olefins have been studied under preparative and equilibrium conditions. At low temperature the olefins react quantitatively giving ...
Chloro- and hydrido-complexes of ruthenium(II) with potassium (4-diphenylphosphino)benzenesulfonate (pTPPMS) were prepared and their properties were compared with those of the related complexes of (3-diphenylphosphino)benzenesulfonates. An X-ray crystal st ...
[Pt-3(mu-CO)(3)(PPh3)(3)] was prepared in high yield by the reaction of [Pt-3(mu-CO)(3)(PPh3)(4)] with H2O2. The carbonyl ligands in [Pt-3(mu-CO)(3)(PR3)(3)] (PR3 = PPh3, PPh(2)Bz, PCy3, P'Pr-3) may be completely replaced by sulfur dioxide to give [Pt-3(mu ...
