Entry point into new trimeric and tetrameric imide-based macrocyclic esters derived from isophthaloyl dichloride and methyl 6-aminonicotinate.
The one-step reaction of isophthaloyl dichloride with the 2-aminopyridine derivative (methyl 6-aminonicotinate) yields (i) a trimer-based macrocycle (EsIO)(3) and (ii) a tetramer-based macrocycle (EsIO)(4) in modest isolated synthetic yields (total of 25%), together with (iii) longer open-chain oligomers. The macrocyclization relies on the semi-flexible imide hinge formed by reaction of the 2-a...
متن کاملElectrodeposited Organic Layers Formed from Aryl Diazonium Salts for Inhibition of Copper Corrosion
Copper substrates deposed on a gold screen-printed electrode were covered with different aryl diazonium salts by electrodeposition at 0.25 mA for 30 or 300 s. Seven compounds were investigated: 4-aminophenylacetic acid, 4-aminophenethyl alcohol, 4-fluoroaniline, 4-(heptadecafluorooctyl)aniline, 4-aminoantipyrine, 4-(4-aminophenyl)butyric acid and 3,4,5-trimethoxyaniline. Quantitative monitoring...
متن کاملBis(μ-2-tert-butylphenylimido-1:2κ2 N:N)chlorido-2κCl-(diethyl ether-1κO)(2η5-pentamethylcyclopentadienyl)lithiumtantalum(V)
In the title compound, [LiTa(C(10)H(15))(C(10)H(13)N)(2)Cl(C(4)H(10)O)], the Ta(V) atom is coordinated by a η(5)-penta-methyl-cyclo-penta-dienyl (Cp*) ligand, a chloride ion and two N-bonded 2-tert-butyl-phenyl-imide dianions. With respect to the two N atoms, the chloride ion and the centroid of the Cp* ring, the tantalum coordination geometry is approximately tetra-hedral. The lithium cation i...
متن کاملDecachlorocyclopentasilanes coordinated by pairs of chloride anions, with different cations, but the same solvent molecules
We have determined the crystal structures of two deca-chloro-cyclo-penta-silanes, namely bis-(tetra-n-butyl-ammonium) dichloride deca-chloro-cyclo-penta-silane di-chloro-methane disolvate, 2C16H36N+·2Cl-·Si5Cl10·2CH2Cl2, (I), and bis-(tetra-ethyl-ammonium) dichloride deca-chloro-cyclo-penta-silane di-chloro-methane disolvate, 2C8H20N+·2Cl-·Si5Cl10·2CH2Cl2, (II), both of which crystallize with d...
متن کاملNovel linear and branched polyamines in the extremely thermophilic eubacteria Thermoleophilum, Bacillus and Hydrogenobacter.
Novel tertiary branched tetra-amines, quaternary branched penta-amines, linear penta-amines and linear hexa-amines were distributed as the major polyamines in six obligately extremely thermophilic eubacteria belonging to Thermoleophilum, Bacillus or Hydrogenobacter. The major polyamine of Thermoleophilum album and Thermoleophilum minutum was identified as a quaternary branched penta-amine, 4,4-...
