Imine aminal

Generally, the addition of chlonne or bromine to tnfluoroacetonitrile leads to a mixture of partially halogenated imines, amines and azo alkanes [270, 271] In special cases, such as the HgF2-mediated addition of bromine, N,N dihaloper-fluoro-2-alkylamines can be obtained in good yields [272]... 

The sequence carbon radical —> imine —> amine is illustrated in equation 30. Irradiation of the pyridinethione 64 (R = cyclohexyl) with the light of a tungsten lamp generates the cyclohexyl radical 65, which was trapped as the imine 67 in the presence of the diazirine 66. The imine was finally hydrolysed to cyclohexylamine80. 

Both aromatic and aliphatic nitroso compounds have been prepared by oxidative procedures. While few of the methods can be considered generally applicable, a sufficient variety of reagents have been proposed that it would appear reasonable to state that virtually any nitroso compound may be prepared by one of these procedures. The organic substrates which have been used are oxaziranes and imines, amines, hydroxylamines, and oximes. A byproduct of the oxidation of 4-methylcinnoline (an azo compound) has also been identified as a dimeric nitroso compound.

Aromatic N-hetcrocyclic substrates (Table 20) are divided between fivc-mcmbered derivatives 222a, having the N—H reactive center not involved in tautomeric equilibria, and five- or six-membered derivatives 222b, in which the reactive N—H group is the aminic form participating in a tautomeric imine-amine equilibrium (Fig. 79) (see also 70, Table 8) ...

In the hydrogenation of aliphatic dinitriles, cyclization can also be an important reaction pathway.92 Saturation of succinonitrile, 45, (Eqn. 19.45) over Raney nickel gave pyrrolidine, 49, as the primary product even in the presence of ammonia. 24 Intramolecular condensation of the imine-amine intermediate is apparently a very facile reaction, taking place in preference to imine hydrogenation and the intermolecular ammonia-imine condensation. The... 

In a number of catalytic reactions, carbon monoxide can serve to eliminate oxygen from organic substrates. In particular, nitrogen-containing functions can be reduced in this way to give imine, amine, or even nitro functions. Accordingly, carbon dioxide is formed in these reactions.

N-Alkyl benzophenone imines. Amines generally react very slowly with aromatic ketones to form imines. However, if titanium tetrachloride is used as catalyst, the reaction of benzophenones proceeds at room temperature in benzene with yields of 75-98%.3...
