Allyl acetate hydroformylation method

The invention discloses an allyl acetate hydroformylation method. The method includes the step that with the existence of a solvent and a catalyst system, a hydroformylation reaction happens to allyl acetate, carbon monoxide and hydrogen, butyraldehyde acetate is generated. The catalyst system comprises a rhodium complex and 6,6'-(3,3',5,5'-4-tert-butylbiphenyl-2,2'-biradical)bis(oxy)bisdibenzo[d,f][1,3,2] dioxaphospholane heterocyclic heptylene . By the adoption of the method, the butyraldehyde acetate is prepared through the allyl acetate in a hydroformylation manner with higher efficiency, and the method has the beneficial effects that the process is simple, the straight-chain product selectivity is high, and catalyst ligands are easy to synthesized.
