used to be one of the most powerful synthetic tools to functionalize alcohols and nitriles, providing valuable N-alkyl amide products. However, this reaction has not been frequently used in modern organicsynthesis due to its employment of strongly acidic and harsh reaction conditions, which often lead to complicated side reactions. Herein, we report the development of a new method using salts of the
A straightforward strategy for direct benzylic C–H bond amination via an electrochemical Ritter-type reaction is developed. The reaction demonstrates simpler and milder reaction conditions over the existing methods without extra mediator. Moderate to excellent yields up to 94% of the desired amide products were obtained with a broad substrate scope. The removal of the Ac group by a simple step can

an environmentally friendly catalyst system is a highly attractive strategy for organicsynthesis. In this work, a H-form mesoporous Beta (H-MBeta) zeolite with an irregular spherical particle shape was synthesized and was found to realize the directamidation of styrene and nitriles for the synthesis of N-alkylated amides in the aqueous phase. This strong acidic H-MBeta catalyst exhibited superior activity
We have developed an efficient, inexpensive, and air-stable catalyst/oxidant (FeCl(2)/NBS) system that could efficiently promote amidation of benzylic sp(3) C - H bonds in ethyl acetate under mild conditions.
