Abstract
The reagents poly(N,N'-dichloro-N-ethylbenzene-1,3-disulfonamide) (PCBS) and N,N,N',N'-tetrachlorobenzene-1,3-disulfonamide (TCBDA) allow the preparation of N,N-dichloroamines, nitriles, and aldehydes from primary amines. A direct oxidative conversion of primary alcohols into nitriles was successfully carried out in aqueous ammonia.
