Triphenylantimony(v) catecholates and o-amidophenolates: reversible binding of molecular oxygen.

Novel neutral antimony(V) complexes were isolated as crystalline materials and characterized by IR and NMR spectroscopy: o-amidophenolate complexes [4,6-di-tert-butyl-N-(2,6-dimethylphenyl)-o-amidophenolato]triphenylantimony(V) (Ph3Sb[AP-Me], 1) and [4,6-di-tert-butyl-N-(2,6-diisopropylphenyl)-o-amidophenolato]triphenylantimony(v) (Ph3Sb[AP-iPr], 2); catecholate complexes (3,6-di-tert-butyl-4-methoxycatecholato)triphenylantimony(V) (Ph3Sb[(MeO)Cat], 3), its methanol solvate 3CH3OH (4); (3,6-di-tert-butyl-4,5-di-methoxycatecholato)triphenylantimony(V) (Ph3Sb[(MeO)2Cat], 5) and its acetonitrile solvate 5CH3CN (6). Complexes 1-7 were synthesized by oxidative addition of the corresponding o-iminobenzoquinones or o-benzoquinones to Ph3Sb. In the case of the phenanthrene-9,10-diolate (PhenCat) ligand, two different complexes were isolated: Ph3Sb[PhenCat] (7) and [Ph4Sb]+[Ph2Sb(PhenCat)2]- (8).

[Extracorporeal detoxication in the treatment of peritonitis complicated with multiple organ insufficiency].

The article deals with experience in the use of filtration and combined methods of extracorporeal detoxification in 201 patients with peritonitis in the phase of polyorganic insufficiency. The methods were developed in the department of abdominal surgery of the Moscow Regional Scientific Research Clinical Institute. The authors show the indications for and the advantages, the mechanisms of the effect, and the results of bifiltration cascade exchange plasmapheresis, improved hemofiltration method, and selective detoxification of portal blood, and the combination of these methods with continuous membrane blood oxygenation.
