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,

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 ...

Lanthanon(III) Amido Complexes
Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1981Abstract Ln(NHCOR)3 (I) and Ln(SCNHCH3)3 (II) are prepared and characterized by elemental analysis, electronic and infrared spectra (Ln = La, Pr, Nd, Sm; R = CH3, C6H5, C5H4N). The bonding of matal to amide is through nitrogen in I while it is through sulphur in II.

Magnesium amido N-heterocyclic carbene complexes
Dalton Transactions, 2008Magnesium dications bind strongly to a tridentate anionic dicarbene ligand L = [N{CH(2)CH(2)(CNCHCHNMes)}(2)] forming dinuclear and trinuclear Mg complexes with some particularly short Mg-C bonds. Treatment of the proligand H(4)LCl(3) with three equivalents of methyl magnesium chloride or benzyl magnesium chloride affords Mg(3)(HL)Cl(6) in high yield ...

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 ...

Functionalized amido ketones: new anticonvulsant agents
Bioorganic & Medicinal Chemistry, 2003We have reported that functionalized amino acids (FAA) are potent anticonvulsants. Replacing the N-terminal amide group in FAA with phenethyl, styryl, and phenylethynyl units provided a series of functionalized amido ketones (FAK). We show that select FAK exhibit significant anticonvulsant activities thereby providing information about the structural ...

Amido analogues of zincocenes and cadmocenes
Dalton Transactions, 2011The 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 ...
