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
结晶的1,3-丙酮二羧酸二烷基酯通过光化学脱羰作用产生的α-羰基对的组合,以高化学收率得到琥珀酸二烷基酯。提出固态反应取决于两个连续的键裂解过程的放热性。还建议固态中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。
