Reductive Deamination of Primary Amines

1-Alkyl-1,2-dihydropyridines thermolyse to complex mixtures, but 1-alkyl-2,3,5,6-tetraphenyl-1,4-dihydropyridines (prepared from the amine and 2,3,5,6-tetraphenylpyrylium salts followed by NaBH4) give alkanes smoothly at ca.200 deg C.Thermolysis of 1-benzyl-2-deuterio-2,4,6-triphenyl-1,2-dihydropyridine gives ω-monodeuteriotoluene (as shown by 2H n.m.r. spectroscopy) indicating a radical mechanism.
