txhais li cas los ntawm Allylation?

Carbonyl allylation yog hais txog rau qhov sib ntxiv ntawm ib qho allyl anion rau ib qho aldehyde lossis ketone los tsim homoallylic cawv, raws li qhia los ntawm cov txheej txheem hauv qab no ob kauj ruam. Thawj qhov kev sib koom ua ke carbonyl tau tshaj tawm xyoo 1876 los ntawm Alexander Zaitsev thiab ua haujlwm rau allylzinc reagent.

Alyl compound yog dab tsi?

Ib pawg allyl yog pawg alkene hydrocarbon nrog formula H2C=CH-CH2 - Nws yog tsim los ntawm ib pawg vinyl, CH2=CH-, txuas rau methylene -CH2 Piv txwv li allyl cawv muaj tus qauv H2C=CH-CH2OH. Cov tshuaj uas muaj cov pab pawg allyl feem ntau hu ua allylic.
