One-pot preparation of 4-aryl-3-bromocoumarins from 4-aryl-2-propynoic acids with diaryliodonium salts, TBAB, and Na(2)S(2)O(8)
Various 4-aryl-3-bromocoumarins were smoothly obtained in moderate yields in one pot by treating 3-aryl-2-propynoic acids with diaryliodonium triflates and K(2)CO(3) in the presence of CuCl, followed by the reaction with tetrabutylammonium bromide (TBAB) and Na(2)S(2)O(8).
