An object of the present invention is to provide a dithioester compound generating an aralkyloxy radical having high ability of abstracting hydrogen. The present invention provides a dithioester compound represented by a formula (1).
[In the formula (1), R
1
and R
2
each independently represent an alkyl group having 1 or more carbon atoms, an alkenyl group having two or more carbon atoms, an alkynyl group having two or more carbon atoms, an aryl group having 6 or more carbon atoms and optionally having a substituent group, an aralkyl group having 6 or more carbon atoms, a hydrogen atom, or a halogen atom; R
3
represents an aryl group having 6 or more carbon atoms and optionally having a substituent group, or an aralkyl group having 6 or more carbon atoms and optionally having a substituent group.]
本发明的一个目的是提供一种生成具有高氢抽取能力的芳基氧自由基的二硫酯化合物。本发明提供了一种由式(1)表示的二硫酯化合物。
[在式(1)中,R1和R2分别独立表示具有1个或更多个碳原子的烷基基团,具有两个或更多个碳原子的烯基基团,具有两个或更多个碳原子的炔基基团,具有6个或更多个碳原子并且可选地具有取代基团的芳基基团,具有6个或更多个碳原子的芳基基团,氢原子或卤素原子;R3表示具有6个或更多个碳原子并且可选地具有取代基团的芳基基团,或具有6个或更多个碳原子并且可选地具有取代基团的芳基基团。]
