- Cobalt(II) phthalocyanine-catalyzed highly chemoselective reductive amination of carbonyl compounds in a green solvent
-
Cobalt phthalocyanine has been employed for the highly chemoselective reductive amination of aldehydes and ketones in ethanol as a green solvent. A large range of functional groups such as nitro, acid, amide, ester, nitrile, halogen, lactone, methoxy, hydroxy, alkene, N-benzyl, O-benzyl and heterocyclic rings were well tolerated under the present reaction conditions.

- Synthesis of substituted amines and isoindolinones: Catalytic reductive amination using abundantly available AlCl3/PMHS
-
AlCl3 has been employed for highly chemoselective reductive amination of carbonyl compounds in ethanol using polymethylhydrosiloxane as an inexpensive, stable and safe reducing agent without an inert atmosphere. A large range of functional groups such as nitro, carboxylic acid, acetyl, nitrile, halogen, methoxy, alkene and heterocycles were well tolerated. AlCl3 also catalyzed tandem amination-amidation of 2-carboxybenzaldehyde with different amines to afford N-substituted isoindolinones. The catalyst can be recycled at least three times without any significant effect on activity and selectivity.
