Accompanied by a change in color from red to black, the enantiomorphic phases of cobalt complexes chiral salen ligand (L2?, Co(L)·CS2, and Co(L) (L = LS,S or LR,R)) chemisorb NO (g) at atmospheric pressure rt over hours for CS2 solvated phase, within seconds desolvated phase. is installed as an axial nitrosyl ligand. Aligned but unconnected voids desorbed Co(LR,R)·CS2 structure indicate conduit...
توسعه روش های محاسباتی امکان مطالعه سیستم های مختلف با دقت کافی را فراهم ساخته است. در این پژوهش با استفاده از محاسبات تئوری تابع دانسیته dft، مکانیسم انعطاف پذیری لیگاندهای سیکلوپنتادی انیل وایندنیل درکمپلکس های (?5-c5h5)fe(co)2(?1-c5h5)(i)،(?5-c5h5)fe(co)2(?1-indenyl)(ii)و (?5-indenyl)fe(co)2(?1-indenyl) (iii) برای بررسی دقیق این مکانیسم به موارد ذیل پرداخته شد. 1) جابه جایی 5و1 در کمپلکس...
We report the synthesis of the first 2',3'-diamino substituted uridine derivative with xylo-configuration, its use as starting material for the synthesis of salen-type ligands and the first structurally characterised copper(II) complex thereof.
The Cover Feature shows “N-amino Benz” (N-(aminobenzyliden)- phthalimide) the protagonist of this article as an enthusiastic young scientist sharing his work. He a molecular redox catalytic reductive reaction discovered with benzyl bromides and chlorides to produce radicals more experienced colleagues in area at informal seminar. After all, it is not that usual have new organic mediator for red...
Reaction of [RuVI(N)(L1)(MeOH)]+ (L1 ) N,N′-bis(salicylidene)-o-cyclohexylenediamine dianion) with excess pyridine in CH3CN produces [Ru(L)(py)2] and N2. The proposed mechanism involves initial equilibrium formation of [RuVI(N)(L1)(py)]+, which undergoes rapid N · · · N coupling to produce [(py)(L1)RuIIINtN-RuIII(L1)(py)]2+; this is followed by pyridine substituion to give the final product. Th...
A chiral Mn(salen) complex exhibiting two lactam binding sites at two rigid 1,5,7-trimethyl-3-azabicyclo[3.3.1]nonan-2-one skeletons is capable of enantioselective sulfoxidation due to spatially remote substrate hydrogen bonding.
background: the incorporation of thallium-201 into 8-hydroxyquinoline was targeted for cell labeling due to interesting physical properties and wide availability of this nuclide as a single photon emission computed tomography (spect) radionuclide. materials and methods: thallium-201 (t1/2=3.04 d) in tl+ form was converted to tl3+ cation in presence of o3/6m hcl and di-isopropyl ether, controlle...
an octahedral cobalt(iii) complex, trans-[(me2bpb)co(bzlan)2]clo4 (1), with h2me2bpb = n,n’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, ir, uv-vis, and 1h nmr spectroscopy. the structure of this complex has been determined by x-ray crystallography. the me2bpb2– is a di-anionic tetradentate ligand furnishing a ...
A new lipophilic Ru salen complex with cholesterol groups can be efficiently incorporated into liposome bilayers, allowing the photoinduced release of nitric oxide (NO) and the membrane transport of NO to coexisting liposomes.
