WebOur last topic for today is the synthesis of amines. While it is possible to make alkyl amines (an example which is a primary amine with a primary alkyl group) would be RCH 2 NH 2) by reaction of a primary halide with ammonia, these reactions are seldom very practical.. The more practical approches to making alkyl amines involve reactions which are reductions. WebPrimary amines have found a wide application in synthesis of compound libraries first of all because of smoothly running amide coupling, arylation, alkylation, reductive amination reactions etc. Using our in-house developed reactivity filters we have selected a range of primary amines that can provide clean reactions and high yields of the products.
