Coinage metal amido and thiolate SNS complexes: consequences of catalyst speciation in Cu(i)-catalysed carbonyl hydroboration

Autor: Saeed Ataie, Maxwell Lohoar, Loïc P. Mangin, R. Tom Baker

Publikováno v: Chemical Communications. 59:4044-4046

Three new IPr-Ag- and -Au-SNS amido and thiolate complexes were synthesized and compared to their previously reported Cu analogues as carbonyl hydroboration catalysts (IPr = bis(2,6-diisopropylphenyl)imidazol-2-ylidene).

Generation of copper fluoroalkyl complexes (CuRFLn) from chlorotrifluoroethylene and −RF transfer to aroyl chlorides

Autor: Luana L.T.N. Porto, Moutasem Seifi, Nicole Johnson, R. Tom Baker

Publikováno v: Canadian Journal of Chemistry.

Given the importance of fluorinated drugs and agrochemicals, fluoroalkylation of organic electrophiles that can be performed at a late stage of chemical synthesis has attracted a flurry of contributions. New fluoroalkyl groups can be obtained by inse

Solvent-free Zn (NSNO) complex-catalysed dihydroboration of nitriles

Autor: Saeed Ataie, Jeffrey S. Ovens, R. Tom Baker

Publikováno v: Chemical Communications. 58:8266-8269

N-donors are the most commonly employed Lewis bases in ligand-assisted catalysis. A dimeric zinc complex (Zn-1) employing a tetradentate pyridine-thioether-anilido-aryloxide NSNO ligand (L) effects the quantitative conversion of nitriles to the corre

Spin-state crossover in photo-catalyzed nitrile dihydroboration via Mn-thiolate cooperation

Autor: Matthew R. Elsby, Changjin Oh, Mina Son, Scott Y. H. Kim, Mu-Hyun Baik, R. Tom Baker

Publikováno v: Chemical Science. 13:12550-12559

The role of a phosphine-free SNS-pincer ligand in metal–ligand cooperative hydroboration catalysis was investigated. The bifunctional thiolate donor and spin-state change to high-spin Mn are crucial to accessing low-energy activation barriers.

SNS ligand-assisted catalyst activation in Zn-catalysed carbonyl hydroboration

Autor: Saeed Ataie, Seth Hogeterp, Jeffrey S. Ovens, R. Tom Baker

Publikováno v: Chemical Communications. 58:3795-3798

Ligands that include Lewis acid/base functionality have extensive applications in bifunctional catalysis using first row metals. In this work, zinc bis(amido), bis(thiolate) and amido-thiolate SNS complexes were prepared and compared as precatalysts

Nickel(II)-SNS Thiolate Complexes: Reactivity and Solution Dynamics

Autor: R. Tom Baker, Jeffrey S. Ovens, Jessica Martin, Yahya M. Albkuri

Publikováno v: Inorganic Chemistry. 60:10934-10942

Nickel coordination chemistry with a biomimetic thiolate-imine-thioether SNSMe ligand is accompanied by diverse reactivity and multidentate ligand dynamics. Reaction of Ni(acac)2 with 2 equiv of 2-(methylthio)-phenyl-benzothiazolidine (MPB) affords t
