چکیده

As the aluminate base [LiAl(TMP)(2)(iBu)(2)] 1 displays halogen tolerance towards substituted aromatics, 4-halo-anisoles have been ortho-aluminated and electrophilically quenched to form synthetically useful multi-heterohalogenated anisoles, with the Al intermediates along the route structurally defined.

Regioselective Iodination of Chlorinated Aromatic Compounds Using Silver Salts.

The iodination of chlorinated aromatic compounds using Ag(2)SO(4)/I(2), AgSbF(6)/I(2), AgBF(4)/I(2) and AgPF(6)/I(2) offers access to iodoarenes that are valuable intermediates in organic synthesis. Specifically, iodination of phenols, anisoles and anilines with a 3,5-dichloro substitution pattern preferentially yielded the ortho, para and para iodinated product, respectively. In the case of ch...

Solvent-free direct ortho C-acylation of phenolic systems by methanesulfonic acid as catalyst

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...

Palladium-catalyzed ortho-halogenations of acetanilides with N-halosuccinimides via direct sp2 C–H bond activation in ball mills

A solvent-free palladium-catalyzed ortho-iodination of acetanilides using N-iodosuccinimide as the iodine source has been developed under ball-milling conditions. This present method avoids the use of hazardous organic solvents, high reaction temperature, and long reaction time and provides a highly efficient methodology to realize the regioselective functionalization of acetanilides in yields ...

Highly regioselective lithiation of pyridines bearing an oxetane unit by n-butyllithium.

The first regioselective ortho-lithiation at the 4-position of simple pyridine derivatives containing a 3-oxetane unit has been achieved using n-butyllithium as base. Electrophilic quenching of the resulting lithio species provides a rapid access to a broad range of new functionalized pyridine oxetane building blocks.
