Catalytic hydroamination of furfuryl and tetrahydrofurfuryl alcohols with nitriles

Reaction of furfuryl and tetrahydrofurfuryl alcohols with nitriles over copper oxide catalysts under a hydrogen pressure of 15 atm at a temperature of 230C gives N-alkylfurfuryl- (yield 46–50%) and N-alkyl-tetrahydrofurfurylamines (49–53%), and N-alkylpiperidines (28–41%). A reaction mechanism is proposed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 23–26, January, 1988.     

Etude photochimique des benzo(A)- et benzo(C)acridines par CIDNP

Photoreactions of benzo(a)- and benzo(c)acridines in protic solvents were studied by CIDNP. Two routes to adducts are possible: direct recombination in the first radical pair (S state) or recombination of radicals after diffusion. The relative importance of each route seems to be linked to the presence of the benzo group and to solvent reactivity.
