{ALF} Details and safety evaluation have been reported for the scale-up of the classical Sandmeyer procedure for the conversion of arylamines to nitriles: Org. Process Res. Dev., 6, 1059 (2004). For a non-aqueous alternative to the Sandmeyer reaction, using alkyl nitrite and CuCN in DMSO, see: Tetrahedron, 52, 7137 (19

{ALF} Aryl bromides and iodides are converted to nitriles by heating with CuCN (the Rosenmund-von Braun reaction). Early procedures were carried out neat at temperatures in excess of 250o; but much better results are usually obtained in refluxing DMF at about 160-170o: J. Org. Chem., 26, 2522 (1961). The product is often obtained as a Cu(I) complex. Alternative methods of decomplexation are described (same ref.) using excess NaCN, or, more conveniently, either oxidation to Cu(II) with FeCl3, chelation with ethylenediamine. For a review, see: Chem. Rev., 87, 779 (1987). For alternative methods for conversion of aryl halides and triflates to nitriles, see Tetrakis(triphenylphosphine)palladium(0), 10548 and L15836. For a review of palladium- and copper-catalyzed cyanation reactions, see: Eur. J. Inorg. Chem., 3513 (2004).

{ALF} Reacts with alkyllithiums to give either "lower order" organocuprates RCu(CN)Li, or, more usefully, the "higher order" reagents R2Cu(CN)Li2. For studies of the structure of higher order cuprates, see: J. Org. Chem., 60, 4310, 4312 (1995). These can undergo coupling reactions with primary or secondary alkyl halides: J. Am. Chem. Soc., 103, 7672 (1981); J. Org. Chem., 48, 3334 (1983); 1,4-addition to ɑß-unsaturated carbonyl groups: Tetrahedron Lett., 23, 3755 (1982); J. Org. Chem., 49, 3938 (1984); Org. Synth. Coll., 8, 112 (1993); and attack epoxides at the less hindered position: J. Am. Chem. Soc., 104, 2305 (1982); J. Org. Chem., 49, 3938 (1984); Org. Synth. Coll., 8, 33 (1993).
