Abstract

Abstract Vacuum Flash Pyrolysis (VFP) at ca. 450–500 C and ca. 0.1–0.3 Torr of the spirocyclic malonyl peroxides (2a, b) affords high yields of allenes (5a, b), while the simple malonyl peroxide (2c) leads to ketone (4), derived respectively from decarboxylation and decarbonylation of the intermediary α-lactones (3).
