Aminated and recycled: Palladium/imidazolium phosphane catalysts enable efficient and general aminations of arylhalides, including direct amination with ammonia. Subsequent recycling is possible without any additional heterogenization (see scheme).

This invention relates to TASK-1 and/or TASK-3 antagonists and/or their pharmaceutically acceptable salts, compositions and methods for treating and preventing disorders which are caused by activation or by an activated TASK-1 and/or TASK-3, and disorders which have TASK-1 and/or TASK-3-related damage as a secondary cause.
Mesure des barrieres d'interconversion entre les deux conformeres enantiomeres de torsion par spectrometre RMN 1 H et 13 C. On montre que les substituants electrodonneurs et electroattracteurs en position 4 augmentent et diminuent respectivement la barriere d'interconversion des napthyl-1 amines tertiaires

Upon irradiation N-alkyl- andN-aryl-1,4-dihydro-1,4-iminonaphthalene derivatives undergo photoisomerization to give mainly azatricycloundecatetraene and/or naphthalene derivatives depending upon the substituents on the nitrogen atom and the aromatic ring.
