Literature References
For an example of the Adams modification of the Gattermann reaction for formylation of aromatics, see: Org. Synth. Coll., 3, 549 (1955). For in situ cyanosilylation of aldehydes and ketones with Zn(CN)2 and TMS chloride, as an alternative to Trimethylsilyl cyanide, A19598, see: Org. Synth. Coll., 7, 521 (1990).
Used in combination with a Pd(0) catalyst in improved procedures for the cyanation of aromatic halides, instead of the classical Rosenmund-Von Braun (CuCN) method: Synth. Commun., 24, 557 (1994); Tetrahedron Lett., 40, 8193 (1999); 41, 3271 (2000); 45, 1441 (2004). For cyanation of aryl triflates, see: Tetrahedron Lett., 39, 2907 (1998); Synlett, 1207 (1998). For a review of palladium- and copper-catalyzed cyanations, see: Eur. J. Inorg. Chem., 3513 (2003).
