Treatment of RuCl2(PPh3)3 and RuHCl(PPh3)3 with the tin compound CH2C(Me)CHC(Me)CH2SnMe3 gives corresponding acyclic pentadienyl half-sandwich (η5-CH2C(Me)CHC(Me)CH2)RuX(PPh3)2 [X = Cl, (2); H, (3)]. The steric congestion in 2 is most effectively relieved by formation cyclometalated complex (η5-CH2C(Me)CHC(Me)CH2)Ru(C6H4PPh2)(PPh3) (4). Addition 1 equiv PHPh2 to (η5-CH2CHCHCHCH2)RuCl(PPh3)2 (1) affords chiral (η5-CH2CHCHCHCH2)RuCl(PPh3)(PHPh2) (5), while...
The systematic exploration of the synthesis heteropentadienyl metal complexes leads us to study metathesis reaction [(η4-COD)Ir(μ2-Cl)]2 with lithium 2,4-dimethyloxopentadienide, which affords dinuclear Ir0–IrII compound (η4-COD)Ir[η1:1-μ2-η4-CHC(Me)CHC(Me)O)]Ir(η4-COD) (1) a metal–metal bond. COD ligands are coordinated η4 each Ir center, whereas oxopentadienyl ligand is bridging both atoms, allowing formation novel iridapyran complex IrII and bonding Ir0. addition CO, PMe3, PMe2Ph...
The molecule (η5-Me2Pdl)Mn(CO)3 (η5-Me2Pdl = 2,4-dimethyl-η5-pentadienyl) has been prepared by a new method and used as starting material to prepare the molecules (η5-Me2Pdl)Mn(CO)n(PMe3)3–n (n 2, 1) phosphine substitution for carbonyls. first carbonyl is achieved thermally in refluxing cyclohexane, second requires photolysis. At room temperature benzene associative intermediate (η3-Me2Pdl)Mn(CO)3(PMe3) that precedes initial loss of observed. Single-crystal structures are reported all...
For [C(O)NH](N) 2 P(O)-based structures, the magnitude of differences in N—H...O, H...O=P and H...O=C angles has been evaluated when N—H bond lengths, determined by X-ray diffraction, were compared to neutron normalized values maximum percentage difference was obtained, i.e. about 3% for angle even if lengths have a 30% (0.7 Å 1.03 neutron-normalized value). The symmetries crystals are discussed with respect symmetry molecules, as well hydrogen-bonded motifs, role most directional hydrogen...
Thioamidation of various classes carboxamide substrates with Lawesson's reagent under liquid-assisted mechanical activation for the synthesis relevant building blocks is described.
The synthesis of a chiral isothiourea, namely, (4a R ,8a )-3-phenyl-4a,5,6,7,8,8a-hexahydrobenzo[4,5]imidazo[2,1- b ]thiazol-9-ium bromide, C 15 H 17 N 2 S + ·Br − , with potential organocatalytic and anti-inflammatory activity is reported. preparation the heterocycle interest was carried out in two high-yielding steps. hydrobromide salt isothiourea provided suitable crystals for X-ray diffraction analysis, results which are Salient observations from this analysis near perpendicular...
Abstract Two novel BODIPY‐Ugi (boron dipyrromethene) adducts exhibit peculiar room temperature (T=20 °C) H‐1 NMR spectra in that several protons located at the aromatic aniline‐type ring are lost baseline. This observation revealed existence of a dynamic conformational process where rotation around C−N bond is hindered. Variable‐temperature and C‐13 spectroscopic analysis confirmed this conclusion; is, low‐temperature show distinct signals for all four below coalescence, whereas average...
Catalysis mediated by iron complexes is emerging as an eco-friendly and inexpensive option in comparison to traditional metal catalysis. The epoxidation of alkenes constitutes attractive application iron(III) catalysis, which terminal olefins are challenging substrates. Herein, we describe our study on the design biomimetic non-heme ligands for situ generation their evaluation potential catalysts olefins. Since it well-known that active sites oxidases might involve imidazole fragment...
