  丙二酰过氧化物的真空快速热解（VFP）：中间α-内酯的脱羧与脱羰

  摘要：

  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）。

  Silica gel was found to mediate decarboxylation of tetra carbonyl compounds with a free carboxylic group prepared from beta-dicarbonyl compounds and malonyl peroxides. Under solvent-free heterogeneous conditions silica gel effectively acts as a mediator of C-O coupling with further decarboxylation at 120 degrees C.

  The spontaneous reaction of disubstituted malonyl peroxides (MPOs) with methanol affording monopermalonic acid monomethyl esters is fast (minutes) for lower homologues but is sharply decelerated (days) for the higher ones. Spirocyclopropyl-MPO is an exception in which the nucleophilic opening of the spiroactivated cyclopropane ring leads to 2,4-dimethoxy-2-carboxybutanoic acid.
