摘要

Ar·CO2·CH2·CHR1R2型芳香族酯在单线态和三重态下都能进行光消除反应，但在任何多重态下都是低效的。计算了p-MeO·C6H4·CO2·CH2·CHR1R2(R1= Me;R2= H, Me)。吸收和发射数据表明，所研究的所有酯的最低单线态和三重态在性质上都是ππ*。

Type 2 photoelimination reaction of esters of aromatic carboxylic acids

Aromatic esters of the type Ar·CO2·CH2·CHR1R2 are found to undergo a photoelimination reaction from both singlet and triplet excited states, though the process is inefficient from states of either multiplicity. Rate constants for the primary steps are evaluated for the systems p-MeO·C6H4·CO2·CH2·CHR1R2(R1= Me; R2= H, Me). Absorption and emission data suggest that the lowest singlet and triplet states in all the esters studied are ππ* in nature.
