We have developed a general method for reverse aromatic Finkelstein reactions. Good reaction yields were obtained when aryl iodides or aryl bromides were treated with copper halide salts as promoters in a 1-butyl-3-methylimidazolium bromide ([BMIM]Br

Synthesis and Reactivity of 3,5-Diiodo-BODIPYs via a Concerted, Double Aromatic Finkelstein Reaction
Publikováno v:
Organic Letters. 23:8595-8599
3,5-Diiodo-8-aryl-BODIPYs are prepared from the corresponding 3,5-dichloro- and 3,5-dibromo- congeners via a double aromatic Finkelstein reaction with NaI in refluxing propionitrile, in yields from 51 to 100%. Rate enhancement is observed for 3,5-dib
