Cationic telomerization of isobutylene

Polymer Bulletin Aims and scope Submit manuscript

Summary

Cationic telomerization has been attempted by reacting BF3 onto isobutylene in the presence of acetic anhydride: Under proper experimental conditions, we obtained only one product — a cetoester monoadduct CH3COCH2-C(CH3)2-O-COCH3 -. In order to study the initiation step, we have reacted a preformed salt CH3CO+SbF6 − onto isobutylene in the presence of acetic anhydride and shown that the acetylium salt is efficient and that termination by esterification is surprisingly high.
