A Convenient Synthesis of Acyclic 1,n-Diketones (n=5-8) from 2-t-Butylperoxycycloalkanones

Nishinaga, Akira,Rindo, Katsuhiko,Matsuura, Teruo

, p. 1038 - 1041 (1986)

The reaction of organolithium with 2-alkyl-2-t-butylperoxycycloalkanones, readily available from t-butylperoxylation of 2-alkylcycloalkanones, gave 2-t-butylperoxy-1-cycloalkanol derivatives quantitatively, thermal decomposition of which with or without an acid afforded 1,n-diketones (n=5-8) in excellent yields.
