  Catalytic Carbonylation of β-Lactones to Succinic Anhydrides

  摘要：

  A well-defined, highly active and selective catalyst for the synthesis of succinic anhydrides from CO and beta-lactones is reported. At 200 psi of CO, the catalyst [(N,N'-bis(3,5-di-tert-butylsalicylidene)phenylenediamino)Al(THF)2][Co(CO)4] carbonylates beta-propiolactones to succinic anhydrides in high yield. (R)-beta-Butyrolactone is carbonylated to (S)-methylsuccinic anhydride with clean inversion of stereochemistry, while cis-2,3-dimethyl-beta-propiolactone yields exclusively trans-2,3-dimethylsuccinic anhydride. These data are consistent with a mechanism involving nucleophilic attack by [Co(CO)4]- on the beta carbon of the lactone, followed by CO insertion and anhydride formation.

  Catalytic carbonylation of epoxides to beta-lactones was effected by a highly active and selective bimetallic catalyst comprised of a chromium(III) porphyrin cation and a cobalt tetracarbonyl anion. The complex is readily synthesized from commercially available compounds in high yield. Carbonylation of numerous linear epoxides, as well as bicyclic epoxides derived from 8- and 12-membered hydrocarbons, proceeded with high activity, selectivity, and yield.
