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).
真空闪速热解(VFP)的温度约为 450–500°C左右 螺环过氧化丙二酰(2a,b)的0.1–0.3托可提供高产率的丙二烯(5a,b),而简单的丙二酰过氧化物(2c)则可生成酮(4),其分别源自中间α的脱羧和脱羰-内酯(3)。
