Sterically demanding and chiral N,N′-disubstituted N-heterocyclic germylenes and stannylenes

The N,N′-dimesitylene substituted o-phenylenediamine 1 reacts with Sn[N(SiMe3)2]2 under formation of the monomeric N-heterocyclic stannylene 2, while the chiral N,N′-substituted o-phenylenediamine 3 reacts with E[N(SiMesu

Synthesis of o-Arylenediamines through Elemental Sulfur-Promoted Aerobic Dehydrogenative Aromatization of Cyclohexanones with Arylamines

Herein, the first elemental sulfur-promoted aerobic dehydrogenative aromatization of cyclohexanones is described that provides novel access to synthetically useful o-arylenediamines. This protocol complements previous palladium- A nd iodine-catalyzed diarylamine formation from cyclohexanones and anilines.

A facile synthetic route to benzimidazolium salts bearing bulky aromatic N-substituents

An atom-economic synthetic route to benzimidazolium salts is presented. The annulated polycyclic systems: 1,3-bis(2,4,6- Trimethylphenyl)-1H-benzo[d]imidazol-3-ium chloride (1-Cl), 1,3-bis(2,6-diisopropylphenyl)-1H-benzo[d]imidazol-3-ium chloride (2-Cl),

Assessing the ligand properties of 1,3-dimesitylbenzimidazol-2-ylidene in ruthenium-catalyzed olefin metathesis

The deprotonation of 1,3-dimesitylbenzimidazolium tetrafluoroborate with a strong base afforded 1,3-dimesitylbenzimidazol-2-ylidene (BMes), which was further reacted in situ with rhodium or ruthenium complexes to afford three new organometallic products.

Synthesis, characterization, molecular structures, cytotoxic and antibacterial activities of N,N′-diaryl-o-phenylenediamines

The molecular structures of N,N′-2,6-dimethylphenyl-o- phenylenediamine (1), N,N′-2,4,6-trimethylphenyl-o-phenylenediamine (2), N,N′-2,6-diisopropylphenyl-o-phenylenediamine 3a and 3b (dimorph of 3a) have been elucidated by X-ray diffraction as well as characterized by FT-IR, HRMS, 1H, 13C NMR and 2D experiments. The cytotoxic and antibacterial activities of the N,N′-diaryl-o-phenylenediamines (1-3) were tested against human tumor cell lines A431 and MOLT4 and Salmonella typhimurium and Staphylococcus aureus respectively. Compounds 1 and 2 showed higher biological activities than compound 3 in cell line A431 and against S. typhimurium. Tumor cell growing was inhibited with 1 and 2 1.0 μg/mL and 0.5 μg/mL, respectively. The minimal inhibitory concentration against S. typhimurium and S. aureus for both compounds was 0.35 μg/mL. However, all compounds presented very similar activities in cell line MOLT4 (1-3: 0.5 μg/mL) and S. aureus (1-3: 0.35 μg/mL). A decrease of steric hindrance on phenylenediamine derivatives might influence on biological activity.

Electrochemical and spectroelectrochemical studies of C-benzodiazaborolyl- ortho-carboranes

An unexpected synthesis of dihydrophenazines en route to benzimidazolium salts

The oxidation of various N,N'-diarylbenzene-1,2-diamines bearing bulky aromatic substituents with sodium periodate on wet silica gel afforded a series of five new dihydrophenazines instead of the expected cyclohexadiene-1,2- diimines. The reaction most likely proceeds via a 1,6-electrocyclic path and provides a convenient access to an important class of nitrogen heterocycles. Subsequent treatment of the mesityl derivative with chloromethyl pivalate and silver triflate led to the corresponding benzimidazolium salt. Copyright
