By employing superacidic fluoroantimonate ionic liquid (IL), [bmim][Sb(2)F(11)], as catalyst, not only thermodynamically-controlled but also kinetically-controlled Friedel-Crafts alkenylations of arenes with alkynes have been realized for the first time.

Beta zeolite supported on silicon carbide, with high thermal conductivity and high mechanical strength, was successfully used as an active and stable catalyst for Friedel-Crafts reactions in a fixed bed configuration.

A-86929, a dopamine D1 agonist was synthesized with 95% ee in five steps with overall yield of 56% via catalytic enantioselective one-pot aziridination followed by Friedel-Crafts cyclization and a mild Pictet-Spengler cyclization protocol.

Friedel-Crafts allylic alkylation of a wide variety of aromatic and heteroaromatic compounds with allylic alcohols catalysed by AuCl(3) (5 mol%) under mild conditions at room temperature was accomplished in good to excellent yields (up to 99%) and regioselectivity.

Friedel-Crafts acylation of the aryldiazirine with ω-ester-α-acyl halide and successive reduction of the carbonyl group to methylene with triethylsilane and trifluoroacetic acid gave diazirinylated fatty acids. Photoaffinity labeling with the carbene generating precursor, 3-phenyl-3-trifluoromethyldiazirine, has become increasingly important as a photophor. However, the complicated synthesis of...

Southern African countries have a good cultural tourism development potential, and many countries in the region have identifi ed the development of cultural tourism as one of the key growth areas in tourism. A specifi c element of cultural tourism is based on crafts that are sold for visitors in various sites and market places. Crafts and craft markets are relatively visible in the Southern Afr...

the use of methanesulfonic acid as a brønsted acid for direct ortho-acylation of phenols and naphthols proves to be a convenient, more general and direct route to various hydroxyaryl ketones. the route is regioselective, leading to ortho c-acylated products in satisfactory to high yields in most cases. the solvent free reactions described below exhibited environmentally benign in terms of faste...

Abstract The (re)connection of contemporary society with traditional knowledge and its expression, crafts, is a contradictory endeavor in itself. On one hand, crafts are socially perceived as burden, useless part social life, the best case, an exotic remanence past, good only for hobbyists. other UNESCO WIPO stated, knowledge, and, by extension, (or should be) essential humankind’s history, pre...

Chiral squaramides are highly enantioselective catalysts for Friedel-Crafts reaction of indoles with N-tosyl imines, affording 3-indolyl methanamine products in 85-96% yields and 84-96% ees.
