Formic acid at 350 deg C converts pyridine and 4-methylpyridine into products deriving from both αβ and βγ C-C bond cleavages of the pyridine ring.

A study has been made of the vapour-phase reaction of tetrahydrofurfuryl alcohol with ammonia and hydrogen on Cu-, Ni-, Co- and Fe-containing bifunctional catalysts at a temperature of 180-240°C. It has been established that, irrespective of the type of catalyst, the main reaction products are piperidine, tetrahydrofurfurylamine and their derivatives. Copyright
FORMATION OF SULFUR COMPOUNDS IN THE HYDRODENITROGENATION OF PIPERIDINE, PYRIDINE, 1-PENTYLAMINE AND 1-PENT-4-ENYLAMINE ON A NICKEL-TUNGSTEN CATALYST IN THE PRESENCE OF HYDROGEN SULFIDE

Hydrogenations of piperidine, pyridine, 1-pentylamine, and 1-pent-4-enylamine were carried out in an autoclave at 300 deg C on a sulfidized nickel-tungsten catalyst using either pure hydrogen or a mixture of hydrogen with hydrogen sulfide.Hydrogen sulfide was found to raise the degree of conversion of the starting substances and accelerate the hydrodenitrogenation by formation of sulfur compounds; 1-pentanethiol, di(1-pentyl)sulfide, 2-methylthiacyclopentane, thiacyclohexane and other sulfur compounds were detected in the reaction mixtures in the presence of hydrogensulfide.A reaction pathway is suggested of the hydrodenitrogenation of piperidine in the presence of hydrogen sulfide, accounting for the favourable effect of the latter on the hydrodenitrogenation of nitrogen compounds.
