In the presence of Rh(2)(OAc)(4) (OAc = acetate) and TBA(2)WO(4) (TBA = tetra-n-butylammonium), the N-silylation of indole derivatives with hydrosilanes efficiently proceeded to give the corresponding N-silylated indoles in high yields. Pyrrole and carbazole were also N-silylated with the combined catalysts.

Two-dimensional (2D) halide perovskites have outstanding optoelectronic properties, and they feature a variety of organic cation spacers cage A-site cations that can be incorporated into their structures. It has recently been reported the Goldschmidt tolerance factor relaxed expanded in iodide 2D perovskites. Bromide perovskites, whose multilayer structures optical properties are much less stud...

The melting point of a deep eutectic solvent formed from a ternary mixture of ethylammonium bromide (EABr), butylammonium bromide (BABr) and urea is 10 °C, which is almost 40 °C lower than the melting points of binary DESs formed from either EABr:urea or BABr:urea mixtures. This reveals a new route to prepare room temperature DESs via mixing different cations.

We report a new lattice structure of the ionic clathrate hydrate of tetra-n-butylammonium bromide induced by guest CO2 molecules, which is found to provide high CO2 storage capacity. The structure was characterized by a set of methods, including single crystal X-ray diffraction, NMR, and MD simulations.

By the reaction of TBA(4)H(4)[γ-SiW(10)O(36)] (TBA = tetra-n-butylammonium) with AgOAc (OAc = acetate) using dimethylphenylsilane as a reductant in acetone, a unique polyoxometalate containing a discrete octahedrally shaped [Ag(6)](4+) cluster, TBA(8)[Ag(6)(γ-H(2)SiW(10)O(36))(2)]·5H(2)O, could be synthesized, and the molecular structure was determined.

The facile synthesis and electronic properties of two-dimensional hybrid organic-inorganic perovskites (2D HOIPs) make these self-assembled systems an important class energy materials. basic building blocks materials include inorganic lattice frameworks that often consist lead-halide octahedra organic molecules possessing ammonium functional groups. Understanding the coupling between layers is ...

Cyclic carbonates are considered to be green nontoxic intermediates with important applications in polymer synthesis and fuel additives as polar solvents high boiling points. The carbonation of epoxidized vegetable oils is a very step the nonisocyanate polyurethane. This reaction usually performed carbon dioxide presence an ionic liquid that acts both solvent catalyst, most studied catalyst bei...

2D Perovskites In article number 2100495, Hua Yu, Xueqing Xu, and co-workers introduced the mixed organic spacer cation n-butylammonium (BA) 1-naphthalenemethylammonium (1-NMA) in perovskites to manipulate interlayer interactions between bulky cations inorganic slabs, leading an efficient air-stable perovskite solar cell.
