The invention discloses a method for preparing primary amide from olefin, carbon monoxide and ammonia gas. According to the method, olefin, carbon monoxide and ammonia gas are used as raw materials for preparation of primary amide under the action of a catalyst composed of phosphine ligand and a rhodium compound; the used phosphine ligand can guarantee that the rhodium compound uses as the catalyst effectively catalyzes carboamidation of olefin, so high-yield production of primary amide can be realized; and the phosphine ligand also contains N-heteroatoms or/and O-heteroatoms or/and S-heteroatoms. The method is a one-pot synthetic method and is simple in synthesis steps; high yield of primary amide is realized in preparation of primary amide from olefin, carbon monoxide and ammonia gas through carboamidation under the action of the catalyst composed of the phosphine ligand and the rhodium compound; and the catalyst has good catalysis performance and stable service life.
