结晶的1，3-丙酮二羧酸二烷基酯通过光化学脱羰反应产生的α-羰基自由基对的结合以高化学产率得到琥珀酸二烷基酯。提出固相反应取决于两个连续键断裂过程的连续性。研究还表明，在固态下自由基形成的效率取决于取代基对键离解能和自由基稳定能力的影响。
Crystalline dialkyl 1,3-acetonedicarboxylates give dialkyl succinates in high chemical yields by combination of alpha-carbonyl radical pairs produced by photochemical decarbonylation. It is proposed that the solid-state reaction depends on the exothermicity of two consecutive bond cleavage processes. It is also suggested that the efficiency of radical formation in the solid state is determined by the effect of substituents on bond dissociation energies and radical-stabilization abilities.
