Han Chemistry Angewandte Chemie 2024 TLDR WebJan 17, 2013 · In the conversion of primary alcohols to primary amines R − C H X 2 O H R − C H X 2 N H X 2 direct alkylation of ammonia normally is the last thing you want to do in the lab. Under conditions where O H is a good leaving group, i.e. in acidic medium, the nucleophilicity of ammonia is reduced due to protonation.

WebPrevious reports have shown that it can efficiently and selectively convert a variety of primary amines into nitriles under alkaline conditions. (13−17) As shown in Scheme 1, the oxidation of amines to nitriles bears many similarities to the oxidation of alcohols to carboxylic acids, another class of electrochemical reactions NiOOH is well-known … WebHighly direct oxidative cyanation of alcohols provides a promising synthesis route for the cyanide-free synthesis of organic nitriles. It is challenging to explore a noble metal-free catalyst for direct conversion of alcohol to nitrile under ammonia conditions because it is a three-step consecutive reaction. borchard chevron
