    • 4 is referred to as the reagent of choice. However, yields are poor to fair, and low regioselectivities have been observed. For example, the Duff reaction of 2,6-dimethoxyphenol gives 2b in 31% yield. For a representative example, see: Larrow, J. F.; Jacobsen, E. N.; Gao, Y.; Hong, Y.; Nie, X. J. Org.
