Amido Phosphine Complexes of Zinc
Inorganic Chemistry, 2003The 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 ...

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 ...

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, 1995The 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 ...

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, 1994Abstract 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 ...
