PROPIONANILIDE synthesis

14synthesis methods
-

Yield: 81%

Reaction Conditions:

with (difluoroboryl)dimethylglyoximatocobalt(II) bis(acetonitrile);3-cyano-1-methylquinolinium cation in acetonitrile at 20; for 5 h;Inert atmosphere;Irradiation;Green chemistry;

Steps:

43 Example 43
In order to 1 - methyl -3 - cyano quinoline salt as a photosensitizer, to cobalt wo complex 2 makes the cobalt catalyst, 5 ml acetonitrile is added in 2.69 mg (1 × 10-2Mmol) photosensitizer and 2.80 mg (6 × 10-3Mmol) of the cobalt catalyst, the air thickness of cylinder Ar atmosphere, then adding 0.2 mmol benzene (R1, R2, R3, R4 For independent of H) and 0.4 mmol propionamide (R is CH2CH3). At room temperature, high-pressure mercury lamp irradiation 5 h. After the reaction, GC (TCD) for detecting H2 The output, GC (FID) for the conversion of the examination benzene, then column separation. Nuclear magnetic hydrogen and mass spectrometry identification of product is aniline N - phenyl propionamide. The conversion of benzene is 83%, N - phenyl propionamide yield is 81%, H2 The yield is 78%.
