| titleOfInvention | A kind of 3- sweet-smelling formacyl difluoro methylene allyl phosphonic acid ester and its synthetic method |
| abstract | The invention discloses a kind of 3- sweet-smelling formacyl difluoro methylene allyl phosphonic acid ester and its synthetic method, shown in the 3- sweet-smelling formacyl difluoro methylene allyl phosphonic acid ester structure formula such as following formula (1): Wherein: substituent R 1 , R 2 For alkyl or R 1 R 2 It is connected to C 3 ‑C 6 Alkylidene, Ar are phenyl, substituted phenyl or heteroaryl.Compared with the existing technology; the method of the present invention is a kind of efficient, simple, high regio-selective synthesis 3- sweet-smelling formacyl difluoro methylene allyl phosphonic acid ester method; this method simplicity, mild condition, good yields; the yield of object can reach 65%-85%; regioselectivity is high, occurs in connection 2,3 double bonds of alkene to hydroacylation reaction selectivity; acyl group is added in connection alkene middle carbon, and palladium catalyst is cheap and easy to get in the method. |
