A Bottleable Imidazole-Based Radical as a Single Electron Transfer Reagent

Reduction of 1,3-bis(2,6-diisopropylphenyl)-2,4-diphenyl-1H-imidazol-3-ium chloride (1) resulted in the formation of the first structurally characterized imidazole-based radical 2. 2 was established as a single electron transfer reagent by treating it with an acceptor molecule tetracyanoethylene. Moreover, radical 2 was utilized as an organic electron donor in a number of organic transformations such as in activation of an aryl-halide bond, alkene hydrosilylation, and in catalytic reduction of CO2 to methoxyborane, all under ambient temperature and pressure.

Interactions of C?F Bonds with Hydridoboranes: Reduction, Borylation and Friedel–Crafts Alkylation

The stoichiometric reactions of the alkylfluorides 1-fluoroadamantane (Ad-F), fluorocyclohexane (Cy-F), 1-fluoropentane (Pent-F) and benzyl fluorides with secondary boranes pinacolborane (HBpin), catecholborane (HBcat), 9-borabicyclo(3.3.1)nonane (9-BBN)

Carbodiimides as catalysts for the reduction of CO2 with boranes

Carbodiimides catalyse the reduction of CO2 with H-BBN or BH3·SMe2 to give either mixtures of CH2(OBBN)2 and CH3OBBN or (MeOBO)3 and B(OMe)3 under mild conditions (25-60 °C, 1 atm CO2). Stoichiometric reactions and theoretical calculations were performed to unveil the mechanism of these catalytic processes.

Metal-free disproportionation of formic acid mediated by organoboranes

In the presence of dialkylboranes, formic acid can be converted to formaldehyde and methanol derivatives without the need for an external reductant. This reactivity, in which formates serve as the sole carbon and hydride sources, represents the first exam

Phosphine catalyzed reduction of CO2 with boranes

Phosphine is shown to catalyse the reaction of CO2 with 9-BBN to give mixtures of HCO2(B(C8H14)) 3, H 2C(OB(C8H14))24 and MeOB(C 8H14) 5; at 0.02 mol% of tBu3P 5 is obtained in 98% yield at 60 °C with TON of almost 5500 and a TOF of 170. Under stoichiometric conditions the species (R3PCH2O)(HC(O)O) B(C8H14) (R = tBu 1,4-MeC6H42) were isolated and characterized. the Partner Organisations 2014.

Pincer-ligated nickel hydridoborate complexes: The dormant species in catalytic reduction of carbon dioxide with boranes

Nickel pincer complexes of the type [2,6-(R2PO) 2C6H3]NiH (R = tBu, 1a; R = iPr, 1b; R = cPe, 1c) react with BH3·THF to produce borohydride complexes [2,6-(R2/su

Frustrated lewis pair inspired carbon dioxide reduction by a ruthenium tris(aminophosphine) complex

Frustrating ruthenium: The ruthenium complex 1 is shown to bind carbon dioxide or aldehyde in a manner similar to a frustrated Lewis pair. Compound 2 catalyzes the reduction of CO2 in the presence of pinacolborane (HBpin), yielding MeOBpin and O(Bpin)2 (see picture; Ru red, P orange, N green, O light red, C black). Copyright

Catalytic properties of nickel bis(phosphinite) pincer complexes in the reduction of CO2 to methanol derivatives

A new nickel bis(phosphinite) pincer complex [2,6-(R2PO) 2C6H3]NiCl (LRNiCl, R = cyclopentyl) has been prepared in one pot from resorcinol, ClP(C5H 9)2, NiCl2, and 4-dimethylaminopyridine. The reaction of this pincer compound with LiAlH4 produces a nickel hydride complex, which is capable of reducing CO2 rapidly at room temperature to give a nickel formate complex. X-ray structures of two related nickel formate complexes LRNiOCHO (R = cyclopentyl and isopropyl) have shown an "in plane" conformation of the formato group with respect to the coordination plane. The stoichiometric reaction of nickel formate complexes LRNiOCHO (R = cyclopentyl, isopropyl, and tert-butyl) with catecholborane has suggested that the reaction is favored by a bulky R group. LRNiOCHO (R = tert-butyl) does not react with PhSiH3 at room temperature; however, it reacts with 9-borabicyclo[3.3.1]nonane and pinacolborane to generate a methanol derivative and a boryl formate species, respectively. The catalytic reduction of CO2 with catecholborane is more effectively catalyzed by a more sterically hindered nickel pincer hydride complex with bulky R groups on the phosphorus donor atoms. The nickel pincer hydride complexes are inactive catalysts for the hydrosilylation of CO 2 with PhSiH3.

Dithiocarboxylic Acids and Derivatives from Carboxylic Esters and Lactones with the Organoboron Sulfide Reagent (9-BBN)2S

Bis(1,5-cyclooctanediylboryl) sulfide (1) reacts with carboxylic esters to give the dithiocarboxylic 1,5-cyclooctanediylboryl esters 2a-f in high yields (2a: X-ray crystal structure analysis).Methanolysis of 2a-f leads to the dithiocarboxylic acids 5a-f, which form the corresponding piperidinium salts in the presence of piperidine.When cyclic esters (γ-, δ-lactones) are allowed to react with 1, the boryloxy-substituted dithiocarboxylic 1,5-cyclooctanediylboryl esters 3a-c are obtained.Key Words: (9-BBN)2S, reagent / OC-Sulfoborations / 1,2-Eliminations, of R2BOR', (R2B)2O / Dithiocarboxylic 1,5-cyclooctanediylboryl esters / Dithiocarboxylic acids
