Reaction progress analysis: Powerful tool for understanding suzuki-miyaura reaction and control of polychlorobiphenyl impurity

Cross coupling of unsaturated aryl or vinyl triflates/halides with aryl boronic acids using Pd as catalyst (Suzuki coupling) have become increasingly attractive for making the heterocoupled product (Ar-Ar′). However, most Pd cycle reactions produce some h

Regioselective Three-Component Synthesis of Vicinal Diamines via 1,2-Diamination of Styrenes

The vicinal diamine motif plays a significant role in natural products, drug design, and organic synthesis, and development of synthetic methods for the synthesis of diamines is a long-standing interest. Herein, we report a regioselective intermolecular three-component vicinal diamination of styrenes with acetonitrile and azodicarboxylates. The diamination products can be produced in moderate to excellent yields via the Ritter reaction. Synthetic applications and theoretical studies of this reaction have been conducted.
