Palladium catalyzed isomerization of alkenyl succinic anhydride and palladium catalyzed reaction of alkenyl succinic anhydride and olefines producing alpha-alkyl, amp;bgr;-alkenyl succinic anhydride

摘要

A process for preparing alkyl maleic anhydrides which - comprises heating a lower alkenyl succinic anhydride in the -presence of a catalytic amount of a palladium salt in -combination with a weakly basic material under conditions -effective to isomerize the alkenyl succinic anhydride.
