A chiral containing imine pyridine oxazoline compounds and its preparation method

The invention discloses a synthetic compound comprising iminopyridyl oxazoline, a preparation method thereof, a metal complex of the compound and application of a prochiral organic compound which contains at least one carbon/carbon or carbon/heteroatomic

Chiral compound containing imine pyridine imidazoline and preparation method, and metal complex

The invention discloses a chiral compound containing imine pyridine imidazoline and a preparation method, and a metal complex. An SP2 carbon atom in an imidazole ring is connected to a site 2 of pyridine and imine is connected to a site 6 of pyridine. The invention also relates to the metal complex of the compound as well as use of the metal complex as a catalyst in a chemical reaction of region selectivity and optical selectivity, in particular a hydrosilation reaction or a dehydrogenizing hydrosilation reaction of an organic compound containing at least one carbon/carbon or carbon/heteroatom double bond. The chiral or non-chiral organic compound prepared by the preparation method is an active substance or is used for preparing an intermediate of the substance, and is in particular used for production of spices and flavoring substances, pharmaceutic preparations and agricultural chemicals.

Trifunctional pNHC, Imine, Pyridine Pincer-Type Iridium(III) Complexes: Synthetic, Structural, and Reactivity Studies

Iridium(III) complexes with a trifunctional pincer ligand containing protic N-heterocyclic carbene (pNHC), pyridine, and imine donor groups were obtained in two sequential steps: (i) protonation of 2-(1-(2,6-diisopropylphenylimino)ethyl)-6-(1-imidazolyl)pyridine (LCH; the superscript specifies the position of the tautomerizable H atom in the imidazole ring) with HBF4·Et2O to give the imidazolium salt [HLCH]+[BF4]- (protonation always occurs at the imidazole N atom) and (ii) metalation of the latter with [Ir(cod)(μ-Cl)]2 to give the hydrido pincer complex [Ir(H)(Cl)(NCMe){LNH-κ3Nimine,NPy,CNHC}]+[BF4]- (3+[BF4]-). Substitution of MeCN in 3+[BF4]- by treatment with triisopropylphosphine gave the analogue [Ir(H)(Cl)P(i-Pr)3{LNH-κ3Nimine,NPy,CNHC}]+[BF4]- (4+[BF4]-). Chloride abstraction from 3+[BF4]- by AgBF4 gave [Ir(H)(NCMe)2{LNH-κ3Nimine,NPy,CNHC}]2+[BF4-]2 (52+[BF4-]2). The centrosymmetric dinuclear Ir(III) complex [Ir(H)(NCMe){μ-(LCH-H)-κ3Nimine,NPy,C2,κN3}]22+[B(C6F5)3F-]2 (62+[B(C6F5)3F-]2) was obtained after deprotonation of 52+[BF4-]2 with KO-t-Bu, followed by addition of B(C6F5)3. It contains two Ir pincer moieties, each with a Nimine,NPy,C2 donor set, which are connected by the Ir-N bonds involving the imidazolide rings, leading to a μ-C,N bridging mode for the latter. Remarkably, all of the donor atoms in the tetradentate bridging chelating ligands are chemically different. The molecular structures of 3+[BF4]-·CH2Cl2, 4+[BF4]-·CH2Cl2, 52+[BF4-]2·2CH2Cl2, and 62+[B(C6F5)3F-]2·4CH2Cl2 have been determined by X-ray diffraction.

Dual-Stereocontrol Asymmetric Cobalt-Catalyzed Hydroboration of Sterically Hindered Styrenes

An oxazoline aminoisopropylpyridine (OAP) was designed and synthesized for cobalt-catalyzed asymmetric hydroboration of sterically hindered styrenes. A unique dual-stereocontrol phenomenon was observed using a rigid OIP·CoCl2 complex or a flexible OAP with CoCl2 as precatalysts, respectively. The reaction could be easily carried out on a gram scale to afford chiral alkylboronic esters which could be converted into diverse C-X (X = C, N, O) bond cross-coupling products. The mechanistically distinct pathways were proposed on the basis of deuterium experiments.

Oligomerisation of ethylene to linear α-olefins by tetrahedral cobalt(II) precursors stabilised by benzo[b]thiophen-2-yl-substituted (imino)pyridine ligands

On activation by MAO, 2-(imino)pyridine cobalt dichlorides bearing a benzo[ b ]thiophen-2-yl substituent in the 6-position of the pyridine ring oligomerise ethylene to α-olefins with turn-over-frequencies as high as 1.5 × 106 mol of C2H4 converted (mol of Co × h)-1 and productivities as high as 3769 kg of oligomers (mol of Co × h × bar)-1. Aldimine precursors are more active than ketimine analogues, yet ketimines give higher molecular weight oligomers.
