2-[[tris(hydroxymethyl)methyl]aminomethylene]cyclohexa-3,5-dien-1(2H)-one and its 6-hydroxy and 6-methoxy derivatives.
The title compounds adopt the keto-amine tautomeric form, with the formal hydroxy H atom located on the N atom, and the NH group and oxo O atom display a strong intramolecular N-H. Expand
The crystal structure of the title compound, C14H13ClN2O, determined at 213 K, shows that the mol­ecule is approx­imately planar in the solid state, having a trans configuration with respect to theExpand
Crystal structures and spectroscopic behavior of monomeric, dimeric and polymeric copper(II) chloroacetate adducts with isonicotinamide, N-methylnicotinamide and N,N-diethylnicotinamide
Abstract Substituted pyridines provide structural rigidity and thus permit the metal coordination geometry to guide the direction of propagation of the hydrogen-bonded links between building blocks.Expand
Hexaphosphanylamine Ligands: 1,1,4,7,10,10-Hexakis(diphenylphosphanyl)-triethylenetetramine Complexes of Chromium, Molybdenum, and Tungsten†
The oligophosphanylamine ligand 1,1,4,7,10,10-hexakis(diphenylphosphanyl)triethylenetetramine (1) was obtained from the reaction of triethylenetetramine with six equivalents ofExpand
The versatile reactivity of cyclo-(P5tBu4)- with complexes of the nickel triad.
complexes 3-5 and 7-9 were characterised by (31)P NMR spectroscopy, and X-ray structures were obtained for 5-9, which gives 8, but always as an inseparable mixture with 7. Expand
2‐Carbaborane‐3‐phenyl‐1H‐indoles—Synthesis via McMurry Reaction and Cyclooxygenase (COX) Inhibition Activity
Despite the lability of carbaboranes under reducing conditions, 2‐ carbaborane‐3‐phenyl‐1H‐indoles could be synthesized by McMurry cyclization of the corresponding amides, and an ortho‐carbaboranyl analogue was active, but showed a selectivity shift toward COX‐1. Expand
Alkali metal reduction of 2-halogeno- and 2-thiolato-2,3-dihydro-1H-1,3,2-diazaboroles
The reduction of 2-bromo-1,3,2-diazaborole tBuNCHCH(tBu)BBr (4c) with a potassium mirror in 1,2-dimethoxyethane afforded a non-separable 1 ∶ 2 ∶ 1 mixture of the compounds tBuNCHCHN(tBu)BH (5),Expand
Crystal structure, spectral and thermal properties of 2-aminopyridinium adipate monoadipic acid dihydrate
Abstract In the title complex, C 22 H 36 N 4 O 10 , cyclic eight-membered hydrogen bonded rings exist involving 2-aminopyridinium and adipate ions. Adipic acid molecules and adipate ions are linkedExpand
N, N, N′, N′‐Tetrakis(diphenylphosphanyl)‐1, 3‐diaminobenzene as a Bis‐chelate Ligand in [1, 3‐{cis‐Mo(CO)4(PPh2)2N}2C6H4]
1, 3-Diaminobenzene reacts readily with PPh2Cl to give N, N, N′, N′-tetrakis(diphenylphosphanyl)-1, 3-diaminobenzene (1) in excellent yield. The dinuclear complex [1, 3-{cis-Mo(CO)4(PPh2)2N}2C6H4]Expand
