✦ Synopsis
Olefin-Insertion Reaction Between the Carbonyls of Benzils; Formation of 1,4-Diketones by Michael Addition Catalyzed by Cyanide Ion. -A novel Michael addition type olefination-insertion reaction between the carbonyl groups of benzils (I) affording 1,4-diketones (III) is described. Cyanide ion is required as catalyst and Bu4NCN is proved to be the most effective cyanide ion donating compound. In a similar manner, aldehyde (IV) undergoes C-O-group insertion to give (V).
