Use of Pol–PPh₃/I₂ for synthesis of amides and Weinreb amides.^[a]

Entry	Acid	Amine	Time	Yield
1			2 h	75%[21]
2			2 h	72%[25]
3			1 h	65%
4			11 h 3 h	57%[20] 71%[b]
5			6 h	53%[41]
6			50 min 1 h	53%[42] 78%[b]
7			1 h	76%[32,c]
8			1 h	79%[39h,c]

^[a]Reactions were conducted using 1 mmol each of Pol–PPh₃ (2.28 mmol/g loading), I₂ carboxylic acid, amine, and 1.5 mmol of iPr₂NEt in 4 mL of CH₂Cl₂, unless specified otherwise.

^[b]Yield obtained by using 2 molar equiv each of Pol–PPh₃ and I₂.

^[c]2.5 Molar equiv of iPr₂NEt was used.
