Bis(dialkylamino)acetonitriles 2a-d react with acetyl chloride and antimony pentachloride to give N,N,N',N'-tetraalkylformamidinium hexachloroantimonates 5a-d.Reaction of p-nitrophenol with 2a,b affords N,N,N',N'-tetraalkylformamidinium salts 8a,b, while reaction of aromatic aldehydes 11 with compounds 2 gives aryl(dialkylamino)acetonitriles 12.Phenyl isothiocyanate reacts with the nitriles 2a-c to give 1:1 adducts for which the structure of N,N,N',N'-tetraalkylformamidinium cyano-N-(phenyl)thioformamidates 19 is proposed.N,N,N',N'-Tetraalkylformamidinium p-toluenesulfonates 30a,b have been prepared from nitriles 2a,b and methyl p-toluoenesulfonate (28).Alkylation of 2c with 28 at higher temperatures affords 1,1-dimethylpiperidinium p-toluoenesulfonate (34) and a small amount (1-piperidinyl)malonodinitrile (33).The nitrile 2a reacts with CH acidic compounds such as ethyl cyanoacetate, malonodinitrile and benzyl cyanide to form the enamines 38.
