摘要

Abstract The combination of PPh 3/I 2 has been shown to be effective for the conversion of a range of carboxylic acids into secondary, tertiary, and Weinreb amides. Simplification of the procedure was possible with the use of polymer-supported PPh 3/I 2. Weinreb amides produced with the use of polymer-supported PPh 3 could be filtered through a short silica gel plug and used in further transformations. Thus, the use of polymer-supported PPh 3 ...
