• Thiocyanogen bromide can be generated in situ by reaction with bromine in acetic acid, e.g. in the thiocyanation of N,N-dimethylaniline to 4-N,N-dimethylaminophenylisothiocyanate: Org. Synth. Coll., 2, 574 (1943).
• Also useful for the conversion of arylamines to thioureas either indirectly via benzoyl isothiocyanate: Org. Synth. Coll., 3, 735 (1955), or directly, but in lower yield, by reaction of ammonium thiocyanate with the amine in the presence of HCl: Org. Synth. Coll., 4, 180 (1963).
• In combination with CAN in t-butanol, epoxides are converted to thiiranes in high yield: Synthesis, 821 (1996). The same conversion can also be effected in the presence of SbCl3 in acetonitrile: Indian J. Chem., 38B, 605 (1999). CAN also promotes the direct conversion of activated aryl systems, e.g. indoles, pyrroles and N,N-dialkylanilines to aryl thiocyanates: Tetrahedron Lett., 40, 1195 (1999).
