FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining secondary amides. Method is realised by carbonylation of respective tertiary amines by means of carbon monoxide in presence of catalyst, containing less than 750 parts per million (ppm) of palladium, and halogen-containing promoter.
EFFECT: increased catalytic activity of catalyst with reduction of palladium concentration and increase of reaction selectivity.
