Amido Phosphine Complexes of Zinc

Inorganic Chemistry, 2003
The first examples of amido phosphine complexes of zinc have been prepared. Addition of N-(2-diphenylphosphinophenyl)-2,6-diisopropylaniline (H[NP]) to ZnMe(2) or ZnEt(2) in diethyl ether at -35 degrees C generated the monomeric, three-coordinate [NP]ZnR (R = Me, Et), while the metathesis reaction of ZnCl(2) with [NP]Li(THF)(2) in diethyl ether at -35 ...

Mechanistic studies on the Rh(III)-mediated amido transfer process leading to robust C-H amination with a new type of amidating reagent.

Journal of the American Chemical Society, 2015
Mechanistic investigations on the Cp*Rh(III)-catalyzed direct C-H amination reaction led us to reveal the new utility of 1,4,2-dioxazol-5-one and its derivatives as highly efficient amino sources.

Amido analogues of zincocenes and cadmocenes

Dalton Transactions, 2011
The synthesis and characterisation of low-coordinate zinc and cadmium complexes of the sterically demanding 1,3,6,8-tetra-tert-butylcarbazol-9-yl ligand ((t)Bu(4)carb(-)) are reported. ((t)Bu(4)carb)(2)M (M = Zn 1; M = Cd 2) are the first examples of formally two-coordinate bis-carbazol-9-yl complexes of the Group 12 metals and 2 is the first ...

Comparative Study of Crystal Packing in Amido-Benzoic and Amido-Perbenzoic Acids

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1994
Abstract Hydrogen-bond arrangements in acid and peracid-amides are discussed. The familiar acid dimer motif is observed for these acids and dimers are linked through amide-amide hydrogen-bonds to form ribbon or sheet networks. Peracid dimers are not observed and instead extensive networks are built up from peracid proton to amide carbonyl hydrogen ...

Nickel-Catalyzed Highly Enantioselective Hydrogenation of β-Acetylamino Vinylsulfones: Access to Chiral β-Amido Sulfones.

Organic Letters, 2018
The nickel/( S)-Binapine complex was found to be an efficient catalyst for asymmetric hydrogenation of β-acetylamino vinylsulfones to afford chiral β-Amido sulfones with excellent yields and enantioselectivities (up to 95% yields and >99% ee).

Multiple States of Dimeric Aggregates Formed by (Amido–ethynyl)helicene Bidomain Compound and (Amido–ethynyl–amido)helicene Tridomain Compound

Chemistry – A European Journal, 2012
AbstractAn (amido–ethynyl)helicene bidomain compound and an (amido–ethynyl–amido)helicene tridomain compound were synthesized. The multidomain compounds were designed on the basis of previous findings that amido and ethynyl oligomers form dimeric aggregates with properties orthogonal to each other. Four aggregate states of multidomain compounds, namely,

Pyridyl to amido and amido to pyridyl isomerisation in an isonicotinamide complex of ruthenium(III)

Journal of the Chemical Society, Dalton Transactions, 1995
The reaction of [RuIII(edta)(H2O)]–(edta = ethylenediamine-N,N,N′,N′-tetraacetate) with isonicotinamide (isna) was studied spectrophotometrically at different pH (6–10), isonicotinamide concentrations and ionic strengths. The pyridyl-N-co-ordinated complex [Ru(edta)(isna)]– is stable at low pH (6.0), but undergoes intramolecular isomerisation at high ...
