Reactions of a number of nitriles with camphene in the presence of the heteropoly acids H3PW12O40, H7PMo12O42, and H4SiW12O40 as catalysts were studied. In all cases, N-substitutedamides were obtained in sufficiently high yields.

Chlorosulfites prepared in situ using thionyl chloride react with nitrile complexes of titanium (IV) fluoride to give a one-pot conversion of alcohols into amides. For the first time, amides are obtained from cyclic alcohols with stereoretention. Critical to the design of these new Ti(IV) reactions has been the use of little explored Ti(IV) nitrile complexes which are thought to chelate chlorosulfites
