One-pot NBS-promoted synthesis of imidazoles and thiazoles from ethylarenes in water

A facile and eco-friendly method has been developed for the synthesis of imidazoles and thiazoles from ethylarenes in water. The reaction proceeds via in situ formation of α-bromoketone using NBS as a bromine source as well as an oxidant, followed by trapping with suitable nucleophiles to provide the corresponding products in good yields under metal-free conditions.

Automatic regulation and control type photoelectric conversion molecule and preparation method thereof

The invention provides an automatic regulation and control type photoelectric conversion molecule. The automatic regulation and control type photoelectric conversion molecule comprises an optical switch molecule, an electron donor which is connected to one end of the optical switch molecule through a covalent bond and an electron acceptor which is connected to the other end of the optical switch molecule through an acetylene group, wherein the optical switch molecule is a group comprising a photochromic compound; the electron donor is a group capable of providing electrons; the electron acceptor is a group which has an electron accepting capability and has electronegativity stronger than that of the electron donor and the optical switch molecule. The automatic regulation and control type photoelectric conversion molecule can be used for efficiently collecting solar energy and converting the solar energy into excitation-state electron energy. The automatic regulation and control type photoelectric conversion molecule is of an open structure at an initial state; electrons are transferred to the acceptor from the donor and an optical switch under light illumination; the optical switchis triggered to be automatically closed and charge flowing in the molecule is stopped; excited electrons cannot reflow and compound, so that efficient separation of charges in an organic molecule system is realized; the closed optical switch absorbs light and is converted back to an opening state after the excited electrons are consumed, so that automatic circulation is realized.

Benzylic Bromination-Acetoxylation of Toluenes by Bromide Ion Catalyzed Thermal Decomposition of Peroxydisulfate in Acetic Acid in the Presence of Acetate Ions

Side-chain bromination and acetoxylation of alkylaromatics by halide ion induced decomposition of potassium peroxydisulfate in acetic acid have been studied by product analysis techniques.Catalytic amounts of lithium bromide in the presence of sodium acetate were found effective in promoting benzylic bromination, followed by conversion to the corresponding benzyl acetates by reaction with acetate.The reaction is interpreted to take place by the redox and free-radical chain mechanism involving bromine atoms (ρ = -1.38 vs. ? + for substituted toluenes).In competiti ve experiments, benzyl and 4-nitrobenzyl acetates were found lees reactive than the corresponding toluenes in acetic acid with the couple S2O82-/Br- but more reactive in carbon tetrachloride with N-bromosuccinimide.

The easy preparation of many benzylic bromides using molecular bromine as a halogenating in the presence of catalytic amounts of lanthanum tri-acetate

Many benzylic brominations were easily achieved by molecular bromine in CCl4 in presence of 1 percent of La (OAc)3 and a standard room lighting lamp.The selectivity is excellent except for certain electron-rich systems (p-methylaniline, p-cresol).
