Estereoespezifitate

Kimikan erreakzio bat estereoespezifikoa dela esaten da estereoisomerian baino bereizten ez diren erreaktiboak erreakzionatzean lehenesten denean estereoisomerian bakarrik bereizten diren produktuak sortzea. Esan nahi baita, erreaktiboen estereoisomeriak baldintzatu egiten du produktuen estereokimika. Ezaugarriari estereoespezifitate deritzo[1].

Karbenoen alkenoekiko erreakzioa estereoespezifikoa da alkenoaren geometriari eusten diolako produktuak. Etsenplurako, dibromocarbenoak (:CBr2) cis-2-butenoarekin erreakzionatzen duenean cis-2,3-dimetil-1,1-dibromoziklopropanoa lortzen da, baina trans isomeroarekin erreakzionatzean trans ziklopropanoa lortzen da[2].
