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,

Lithium Dimethyl(amido)zinc Complexes:  Contrasting Zincate (Amido = TMP) and Inverse Zincate (Amido = HMDS) Structures on Addition of TMEDA

Organometallics, 2006
Introducing TMEDA to the lithium dimethyl(amido)zincates “LiZn(NR2)Me2” leads to a discrete ion-contacted zincate with TMEDA bound to lithium in the case of NR2 = TMP but to a novel “inverse zincate” with TMEDA bound to zinc in the case of NR2 = HMDS, where unexpectedly Me2Zn(TMEDA) functions as a η1,μ ligand to dimeric (LiHMDS)2 molecules to afford a ...

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 ...

Hyperbranched poly(amido amine) demulsifiers with ethylenediamine/1,3-propanediamine as an initiator for oil-in-water emulsions with microdroplets

Fuel, 2018
Two kinds of hyperbranched poly(amido amine) (h-PAMAM) with abundant terminal amine groups are synthesized to break the oil-in-water (O/W) emulsions consisting of microdroplets.

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).
