The hydroboration of phenyl vinyl sulfide with catecholborane (HBcat) and pinacolborane (HBpin) has been examined with a number of rhodium complexes, all of which proceed with excellent regiocontrol in favour of the branched product PhSCH(B(OR)2)CH3. The corresponding linear product can be obtained exclusively in reactions employing [Cp*IrCl2]2 and HBcat. Catalysed hydroborations of (E)-2-(p-to...

Treatment of [Et4N][Tp*WS3] (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) (1) with CuX (X = Br, SCN) and PPh3 or 1,1-bis(diphenylphosphino)methane (dppm) produced two neutral trinuclear clusters [Tp*W(μ3-S)(μ-S)2Cu2Br(PPh3)] (2) and [Tp*W(μ3-S)(μ-S)2Cu2(SCN)(dppm)]2·MeCN·Et2O (3·MeCN·Et2O). Reactions of 1 with [Cu(MeCN)4]PF6, NH4PF6 and 1,3-bis(diphenylphosphino)propane (dppp), N,N-bi(dip...

A set of bimetallic complexes based on iridium and rhodium with bis(diphenylphosphino)methane, bis(di-iso-propylphosphino)methane, diphenyl-2-pyridylphosphine 2-(di-iso-propylphosphino)imidazole bridging ligands was prepared. The were characterized by NMR IR spectroscopy studied quantum-chemically using DFT methods. systems succeeded in catalytic hydrodefluorination reactions lower fluorinated ...

Effective liposomal formulations of vinorelbine (5' nor-anhydro-vinblastine; VRL) have been elusive due to vinorelbine's hydrophobic structure and resulting difficulty in stabilizing the drug inside the nanocarrier. Triethylammonium salts of several polyanionic trapping agents were used initially to prepare minimally pegylated nanoliposomal vinorelbine formulations with a wide range of drug rel...

The CoII-catalyzed [2+2+2] cycloaddition of functionalized diynes and phosphaalkynes resulting in the formation an array structurally interesting phosphinines is reported. A combination 1,2-bis(diphenylphosphino)benzene (dppbenz) CoI2 turned out to be most suitable active catalyst system under microwave reaction conditions. Chemoselective cyclizations presence nitriles have been observed, a num...
