Palladium-catalyzed cross-coupling reactions of in situ generated allylindium reagents with aryl halides.
[reaction: see text] In situ generated allylindium reagents from the reaction of 1 equiv of indium with 1.5 equiv of allyl halides could be effective cross-coupling partners in palladium-catalyzed… Expand

The new DO3A-derived dithiocarbamate ligand, DO3A-(t)Bu-CS2K, is formed by treatment of the ammonium salt [DO3A-(t)Bu]HBr with K2CO3 and carbon disulfide. DO3A-(t)Bu-CS2K reacts with the ruthenium… Expand
Aluminum-Catalyzed Cross-Coupling of Silylalkynes with Aliphatic C-F Bonds.
We report the generation of aliphatic and benzylic acetylenes via reaction of primary, secondary, and tertiary aliphatic fluorides with various trimethylsilyl acetylides. These reactions are… Expand
Protonolysis of an α-Hydroxyl Ligand for the Generation of a PCcarbeneP Pincer Complex and Subsequent Reactivity Studies
A rhodium α-hydroxylalkyl complex (1) reacts rapidly with Brookhart’s acid, [H(OEt2)2][B(3,5-(CF3)2-C6H3)4], to generate a cationic PCcarbeneP complex (2). Complex 2 can also be accessed from salt… Expand
Mechanistic Studies on the Copper-Catalyzed N-Arylation of Alkylamines Promoted by Organic Soluble Ionic Bases
Experimental studies on the mechanism of copper-catalyzed amination of aryl halides have been undertaken for the coupling of piperidine with iodobenzene using a Cu(I) catalyst and the organic base… Expand
Facile generation of iridium PCcarbeneP pincer complexes via water elimination from an alcohol proligand.
We report the facile generation of Ir PCcarbeneP pincer systems. These systems are accessed from the reaction between [IrCl(COD)]2 and a bis(diphenyl)phenylene P(OH)P proligand (1) with concomitant… Expand
Convergent (De)Hydrogenative Pathways via a Rhodium α-Hydroxylalkyl Complex
We report the convergent reaction pathways between [RhH(PPh3)4] and POP ketone (1) and alcohol (2) ligands that terminate in the formation of an α-hydroxylalkyl rhodium(I) complex (3), representing… Expand
Synthesis, Characterisation and Reactivity of Copper(I) Amide Complexes and Studies on Their Role in the Modified Ullmann Amination Reaction
A series of copper(I) alkylamide complexes have been synthesised; copper(I) dicyclohexylamide (1), copper(I) 2,2,6,6-tetramethylpiperidide (2), copper(I) pyrrolidide (3), copper(I) piperidide (4),… Expand
Direct oxide transfer from an η2-keto ligand to generate a cobalt PCcarbeneP(O) pincer complex.
We report the direct carbonyl cleavage in a κ3-P',(η2-C,O),P'' ligand by a monomeric cobalt centre through metal-ligand cooperativity. C-O cleavage leads to the formation of a PCcarbeneP(O) pincer… Expand
Catalytic Deoxygenation of Amine and Pyridine N-Oxides Using Rhodium PCcarbeneP Pincer Complexes
Rhodium PCcarbeneP pincer complexes 1-L (L = PPh3, PPh2(C6F5), PCy3) readily facilitate deoxygenation of amine and pyridine N-oxides. The resulting complexes exhibit η2-C═O coordination of the resu...
