method for the preparation of N,3-disubstituted indoles and 3-hydroxyl indolines. This synthetic strategy relies on an epoxide-opening followed by an intramolecular SNAr of the resulting fluoroaryl amino alcohols. The reaction afforded 3-hydroxyl indolines when carried out at lower temperature for the derivatives bearing multi-fluorine substituents at the aromatic ring.

One-Step Synthesis of α-Chloro Acetophenones from Acid Chlorides and Aryl Precursors
A direct and efficient method was developed for the preparation of a variety of substituted acetophenone derivatives from readily available arene precursors and acid chlorides. This method has significant generality and affords access to substitution patterns on aryl rings not directly achievable by Friedel-Crafts chemistry. [reaction: see text].
