  Nucleophilic displacement in 2-chloro(trifluoromethyl)pyridines with amines and ammonia

  摘要：

  The activating effect of trifluoromethyl groups in 2-chloro(trifluoromethyl)pyridines was investigated by comparing reactions of these compounds and of 2-chloropyridine with secondary cyclic amines. The ammonolysis of 2-chloro-3-trifluoromethylpyridine and 2-chloro-4-trifluoromethylpyridine is also reported and shown to proceed, in contrast to the reported behaviour of 2-chloro-5-trifluoromethylpyridine, without hydrolysis of the trifluoromethyl function. Both 2-amino-3-trifluoromethylpyridine and 2-amino-4-trifluoromethylpyridine were converted (via the corresponding pyridones) to 3-trifluoromethylpyridin-2(1H)-thione and 4-trifluoromethylpyridin-2(1H)-thione, and a number of S-alkyl derivatives of the latter compounds were prepared.

  A Ru-catalyzed mono-arylation in alpha-position of saturated cyclic amines is reported employing a C-H activation protocol. Substitution of the pyridine directing group with a bulky group, e.g., trifluoromethyl in the 3-position, proved to be crucial to avoid bis-arylation. This highly selective transformation can be performed with different amines and arylboronate esters. Additionally, the directing group can be cleaved, taking advantage of an unprecedented detrifluoromethylation reaction.
