The title compound, [Cr(C(12)H(27)O(3)SSi)(2)(C(6)H(15)N)(2)], is a mol-ecular chromium(II) thiol-ate that is coordinated by two dipropyl-amine ligands in a square-planar environment. The mol-ecule lies on an inversion site.

An asymmetric normal-electron-demand aza-Diels-Alder cycloaddition of 2-aryl-3H-indol-3-ones and 2,4-dienals was explored via trienamine catalysis of a chiral secondary amine. Multifunctional tricyclic polyhydropyrido[1,2-a]indoles were efficiently constructed in good stereoselectivity (up to 92% ee, >19 : 1 dr).

An efficient synthesis of 2-heteroarylazulene derivatives was established via electrophilic substitution. The reaction of 6-dimethylamino-1,3-di(methylthio)azulene (1a) with the triflate of N-containing heteroarenes proceeded in the presence of excess heteroarenes to afford the corresponding 2-dihydroheteroarylazulene derivatives 3−7. The 2-dihydroheteroarylazulene derivatives were readily conv...

The title compound, C(14)H(21)NO(2)S, synthesized by N-methyl-ation of cyclo-hexyl-amine sulfonamide with ethyl iodide is of inter-est as a precursor to biologically active sulfur-containing heterocyclic compounds. There are two independent mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the phenyl ring and the cyclo-hexyl ring are 40.29 (11) and 37.91 (13)° in...

Binucleating multidentate amine bis(phenolate) ligands with rigid terphenyl backbones were designed to support two zirconium centers locked in close proximity. Polymerizations of propylene or 1-hexene with the synthesized bimetallic precatalysts resulted in polymers with significantly higher isotacticity (up to 79% mmmm) in comparison to the stereoirregular polymers produced with previously rep...

We describe a new class of charge inverted zwitterionic sulfated lipids (AS) with a cationic quaternary amine anchored at the membrane interface and an anionic sulfate moiety extended into the aqueous phase. These lipids have exceptionally high transition temperatures and assemble into lipid aggregates when dispersed in aqueous solutions.

The utilization of 2-(2-nitrophenyl)propyloxycarbonyl (NPPOC) as a photolabile primary amine cage enables the thiol-Michael 'click' reaction to be photo-triggered. The photolabile amine exhibits efficient catalytic activity upon UV irradiation and is shown to initiate the photopolymerization of tetrathiol and diacrylate comonomers via Michael addition.

The title compound, C(9)H(9)N(3)S, was synthesized by the reaction of 4-methyl-benzoic acid and thio-semicarbazide. The thia-diazol ring adopts a planar conformation and makes a dihedral angle of 31.19 (18)° with the phenyl ring. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds.

(N-heterocyclic carbene)gold(I) alkynyls and organic azides have undergone cycloadditions in water-t-butanol mixtures with copper metal as the pre-catalyst to give new gold(I) triazolyls in high purity. Substrate tolerability was outlined for organoazides bearing a range of functional groups, and branching alpha to the azide moiety. All products are validated by combustion analysis or high-reso...

By using ionic liquids as solvents, the chlorination or bromination of unprotected anilines at the para-position can be achieved in high yields with copper halides under mild conditions, without the need for potentially hazardous operations such as supplementing oxygen or gaseous HCl.
