Described herein is a continuous‐flow strategy for the palladium‐catalyzed direct C−H arylation of indole‐3‐acetic acid derivatives with arenediazonium salts. A fully autonomous self‐optimizing flow platform was used to efficiently optimize the coupling reaction in a three‐dimensional space. The flow methodology developed is experimentally simple, mild, broad in scope, and safer than traditional batch

The diazotization of aryl amines at room temperature in paste form with NaNO(2), p-TsOH and a small amount of water, followed by treatment with KI provides a new, simple, and effective route for the preparation of various aryl iodides. The water-paste and strong acid-free reaction conditions are environmentally friendly and compatible with acid-sensitive functional groups. (c) 2007 Elsevier Ltd. All rights reserved.
