The special reactivity of N,N-dialkylaniline N-oxides allows practical and convenient access to electron-rich aryl halides. A complementary pair of reaction protocols allow for the selective para-bromination or ortho-chlorination of N,N-dialkylanilines in up to 69% isolated yield. The generation of a diverse array of halogenated anilines is made possible by a temporary oxidation level increase of N,N-dialkylanilines to the corresponding N,N-dialkylaniline N-oxides and the excision of the resultant weak N-O bond via treatment with thionyl bromide or thionyl chloride at low temperature.

Expedient syntheses of the 3-hydroxy- and 6-hydroxy- derivatives of 11H-benzo[a]-fluoren-11-one, obtained via Suzuki-Miyaura couplings are described. Reactions of these phenols with 1,1-diarylprop-2-yn-1-ols give indeno[2,1-i]- and indeno[1,2-f]-naphtho[2
Preparation of E-(2-substituted-1-methylethylidene)indanones derived from monic acid

Alkylation of the lithium dienolate of the monic acid hydroxamate (3) with o-bromo(bromomethyl) benzene or heteroaromatic derivatives gave α-alkylated products (5). This alkylation procedure was surprisingly catalysed by 4- dimethylaminopyridine. Metal-halogen exchange with t-butyl lithium occurred with concomitant intramolecular cyclisation to give a mixture of the deconjugated ketones (6). Reconjugation with potassium t-butoxide stereoselectively produced the E-isomer (7). Deprotection gave the monic acid derived ketone (1).
