The compositions and structures of several stable nitrile-HCl salts previously reported were reinvestigated. Most of them have been found to have the composition of 2RC≡N·2HCl and have been identified as <I>N</I>-(α-chloroalkenyl)alkylamidine hydrochlorides (<B>3</B>) by mass and NMR spectra analyses. However, the 2:3 adduct from chloroacetonitrile was confirmed to be <I>N</I>-(α,α,β-trichloroethyl)chloroacetamidine hydrochloride. The scope and limitations of the dimerization reaction of nitriles having α-hydrogen with HCl were studied. Most nitriles having α-hydrogen react with HCl to give <I>N</I>-(α-chloroalkenyl)alkylamidine hydrochlorides (<B>3</B>). Their hydrolysis to diacylamines (<B>4</B>) was also investigated.
