[reaction: see text] Functionalized Grignard reagents, derived from readily available o-iodoaniline derivatives and obtained via a straightforward iodine-magnesium exchange, can be used to prepare a wide range of polyfunctional indoles, quinolines, and quinazolinones.
A novel and efficient synthesis of pyrrolo[3,2,1-kl]phenothiazines has been developed through a Cu(I)-catalyzed tandem C–S coupling/double cyclization process. Using 2-alkynyl-6-iodoanilines and o-bromobenzenethiols as the starting materials, a wide range of pyrrolo[3,2,1-kl]phenothiazine derivatives were facilely and efficiently generated in one pot under Cu(I) catalysis.

donor in an arylethynyl bisurea supramolecular anionreceptor and use the Perrin method of competitive titrations to study the deuterium equilibrium isotope effects (DEIE) of anion binding for HS−, Cl−, and Br−. This work highlights the utility and also challenges in using this method to determine EIE with highly reactive and/or weakly binding anions.
