A one-pot N-cyanation of secondaryamines has been developed using trichloroacetonitrile as an inexpensive cyano source. A diverse range of cyclic and acyclic secondaryamines can be readily transformed into the corresponding cyanamides in good isolated yields, with the method successfully utilized in the final synthetic step of a biologically active rolipram-derived cyanamide. This approach exhibits
A mild platinum-catalysed method for the formation of free amidines from the reaction of amines and trichloroacetonitrile in nonpolar solvents has been developed. This protocol provides access to novel amidines that in some cases (4b–d) cannot be synthesised via the direct reaction of amines and halogenated nitriles.
