Simple strategies for decarboxylative functionalizations of electron-deficient benzoic acids via using Cu(I) as promoter and electron-rich ones by employing Pd(II) as catalyst under aerobic conditions have been established, which lead to smooth synthesis of aryl halides (-I, Br, and Cl) through the decarboxylative functionalization of benzoic acids with readily available halogen sources CuX (X = I, Br, Cl), and easy preparation of benzonitriles from decarboxylative cyanation of aryl carboxylic acids with nontoxic and low-cost K4Fe(CN)6 under an oxygen atmosphere for the first time.

supporting information; experimental part, p. 2677 - 2682 (2009/10/20)
New families of monomeric to dendritic, and monocationic to multicationic (PNP) compounds have been prepared and tested as catalysts in halogen exchange (Halex) reactions. Some of them allow an increase in the efficiency of these reactions which are performed in some cases under the mildest conditions reported up to now.
Tetramethylammonium chloride as a selective and robust phase transfer catalyst in a solid-liquid halex reaction: The role of water
Sasson, Yoel,Negussie, Samuel,Royz, Michael,Mushkin, Noam
, p. 297 - 298 (2007/10/03)
Tetramethylammonium chloride (TMAC) is an effective phase transfer catalyst for the selective chloride/fluoride exchange reaction of activated aryl chlorides with potassium fluoride provided that the amount of water in the system is limited and controlled.
