, p. 1001 - 1005 (2007/10/03)
An effective method for the conversion of acids into amides is presented. The two-step procedure includes the preparation of acid chloride intermediates using Pol-Ph3P and subsequent treatment of these intermediates with amines and polymer-bound base. The amides were accessible in high yields and purities without further purification.

On heating with amines or alcohols in the presence of tris(2-methoxyphenyl)- or tris(2,6-dimethoxyphenyl)bismuthine, carboxylic acids bearing α-hydrogen are readily converted into the corresponding amides or esters in good yields while those without α-hydrogen remain intact.
