Question

OS 88 N-Br 064-0 NaOH H2O Br Racemic mixture Scheme 1: Formation of epxoycyclohexane starting with cyclohexene.

Could you please show the full mechanism for this reaction with arrow pushing. Thank you so much!

Answer 1

Answer N-BO OH NaOH von NaOH, D (Racemic mixture) (Eposúde) reaction mechanism: CN-By 05 Fo N Here the Bromine atom has a partial positive charge which make it a good electrophile, 0 -10 ] AU (Nucleophile) (cyclic bromonium in formation)

Na +014 By racemic mixturce) BP as a good leaving group Explanations In this reaction mechanism, when H2o attach to the eyelic boomoniumion, it prefer to attack opposite side of bromine atom bromonium ion. so for that reason, amit racemie mixture formed, on treatment of wooh, which produced 8H in as nucleophile, abstract -oh proton, so it formed hisdroxyl anion, then it reart Pas shown in mechanism ] c. By bond an Bu as a good leaving group and formed epoxide : .
