※ 引述《radiohead627 ( 香蕉勇士)》之铭言：
: 2-cyclohexenone 跟 H2O2 ,NaOH 反应
: 产物是啥?
: 应该不会是epoxide吧 有点怀疑
: thx
you got it!
the C=C of the alpha, beta-unsaturated carbonyl system showed
the polarized electronic nature.
the peroxide, generated from H2O2 and NaOH, is a good nucleophile
for 1,4-addition reaction.
as OOH- attacted on beta-carbon, the enloate back-attacked onto the
peroxide to release a hydroxide and to form the alpha-carbonyl oxirane.

1F：推 radiohead627:我同学说因为carbonyl的关系所以不会形成epoxide 02/13 22:55
2F：推 shok:会啦 应该是epoxide 02/14 00:30
