RhCl3-catalyzed hydroboration of alkenyl nitriles

RhCl3-promoted hydroboration–oxidation reactions of representative alkenyl nitriles have been carried out. Carbanion of acetonitrile is formed from the carboncarbon heterolytic bond breaking in allyl cyanide during hydroboration. An unexpected process-trimerization of carbanion of acetonitrile has lead to the formation of 4-amino-2,6-dimethylpyrimidine.
