All these complexes are characterized fully by their physicochemical characterizations and X-ray structure determination. Notably, the yield of this product is low (5%) at 100 ° C but increases to 25% in refluxing aniline. A separate chemical reaction between aniline and strongly oxidizing tetra- n-propylammonium perruthenate - in air produced a ruthenium complex of a N 4 -tetraamidophenylmacrocycle ligand via multiple ortho- C-N bond fusion reaction. A previously reported complex (5) undergoes similar oxidation by air at 185 ° C to produce complex. Complex and aniline (neat) at 185 ° C produced a bis-chelated ruthenium complex (3). Reaction of aniline with (terpy = 2,2':6',2″-terpyridine) resulted in a trans bis- aniline ruthenium(II) complex which upon oxidation with H 2 O 2 produced compound of a bidentate ligand, N-phenyl-1,2-benzoquinonediimine, due to an oxidative ortho- C-N bond fusion reaction. ![]() In this work, ortho- C-N bond fusion reactions of aniline are followed by the use of two different ruthenium mediators.

The use of 2,3-dihydrotryptamine instead of aniline enabled easy access to 3a-(1-indolyl)pyrroloindoline and the concise synthesis of C3a- N1'-linked pyrroloindoline alkaloid (±)-psychotriasine was accomplished. The cross-coupling of tryptamine with substituted aniline to access C3a-nitrogen-linked pyrroloindolines has been developed via the consecutive cyclization of tryptamine with DMSO/Tf2O and the substitution of 3a-pyrroloindolylthionium intermediate with aniline.

Integrated Risk Information System (IRIS)Ĥ,4 ' - Methylene bis ( N, N ' - dimethyl ) aniline CASRN 101 - 61 - 1 Human health assessment information on a chemical substance is included in the IRIS database only after a comprehensive review of toxicity data, as outlined in the IRIS assessment development process. Composite sensitivity has been found to increase with the increasing concentration of humidity, at room temperature.Ĥ,4\\'-Methylene bis( N,N\\'-dimethyl)aniline An appreciable response was shown in the presence of 40% humid atmosphere for up to successive four cycles. Synthesized poly ( N-ethyl aniline)/Ag nanocomposite exhibited a high response to humidity, good reproducibility and stability at room temperature. FE-SEM photographs reported agglomerated granular particulate nature of poly ( N-ethyl aniline)/Ag nanocomposite. Peaks at 1789cm-1, 1595cm-1, 667cm-1 and 501cm-1 in FTIR spectrum confirmed the formation of poly ( N-ethyl aniline)/Ag nanocomposite. ![]() Characteristic peaks in UV-visible and FTIR spectra of poly ( N-ethyl aniline) switched to higher wave numbers in poly ( N-ethyl aniline)/Ag nanocomposite. XRD spectral study exhibited major diffraction in the range 20-80∘ (2θ) and indicated the semicrystalline nature of poly ( N-ethyl aniline)/Ag nanocomposite. The synthesis of Poly ( N-ethyl aniline)/Ag nanocomposite has been confirmed by X-ray diffraction (XRD), Ultraviolet-Vis Spectroscopy (UV-visible), Fourier transform infrared analysis (FTIR) and FE-SEM investigations. Poly ( N-ethyl aniline)/Ag organic-inorganic composite has been synthesized by a single step in situ chemical oxidative polymerization method. Poly ( N-ethyl aniline)/Ag Nanocomposite as Humidity Sensor ![]() This intermediate then undergoes unimolecular decomposition to generate benzene and N2. We provide evidence that the initial step involves nucleophilic attack of aniline at the nitrido ligand of the ruthenium complex, which is followed by proton and electron transfer to afford a (salen)ruthenium(II) diazonium intermediate. We report experimental and computational studies of the facile oxidative C-N bond cleavage of anilines by a (salen)ruthenium(VI) nitrido complex.
