A practical and efficient method for N-arylation of benz-amides promoted by potassium carbonate in the presence of DMEDA was developed. The reaction was carried out without addition of any transition-metal catalyst to afford a variety of N-arylated products in moderate to good yields (up to 97%).
Revisiting 1-chloro-1,2-benziodoxol-3-one: Efficient: ortho -chlorination of aryls under aqueous conditions

The application of 1-chloro-1,2-benziodoxol-3-one as a powerful chlorinating agent as well as oxidant for aniline derivatives is explored. The amide directing group assisted radical mediated ortho-selective chlorination proceeds in the absence of a radical initiator. Various electronically differentiated anilides and sulfonamides are tolerated under aqueous conditions.
Role of Hetero-halogen (F · · · X, X = Cl, Br, and I) or homo-halogen (X · · · X, X = F, Cl, Br, and I) interactions in substituted benzanilides

experimental part, p. 1578 - 1596 (2012/04/04)
A series of halogen-substituted benzanilides have been synthesized and characterized, and crystallization studies directed toward generation of polymorphs have been performed to delineate the importance of interactions involving halogens. The effect of ha
Copper-catalysed intramolecular O-arylation of aryl chlorides and bromides: a straightforward approach to benzo[d]oxazoles in water

A general, efficient and more sustainable protocol for the copper-catalysed intramolecular O-arylation of o′-haloanilides leading to the benzo[d]oxazole core is reported. Remarkably, the optimised conditions allowed for the use of inexpensive and easily available aryl chlorides as arylating agents. Moreover, all reactions were carried out employing exclusively water as the solvent, rendering the methodology presented herein highly valuable from both environmental and economic points of view.
