有機化學問題protect group

if a compound has two functional groups that will react with a given reagent

and you want only one of them to react , it is nessary to protect the other

functional group from the reagent . a group that protects a functional group

from a synthetic operation that it would not otherwise survive is called a

protecting group

(a) which compound can be used to protect a keto group ?

(b)which compound can be used to protect an alcohol?

請中譯和詳解

    protecting group

    如果一化合物有兩種官能基都可跟反應物反應 但是您卻只想跟其中一個官能基反應 就有必要保護其他官能基免免於反應物 可以保護官能基於合成反應中使之不被活化 稱為保護基

    (a) which compound can be used to protect a keto group ?

    何種化合物可保護酮基(羰基)?

    縮醛或縮酮類

    (b)which compound can be used to protect an alcohol?

    何種化合物可保護醇?

    甲基醚 乙醯基....

    不好意思 我沒讀過保護基...只能網路找點資料來回答您 .....這是高等有機化學的東西?抱歉我只是大學生 如果是高等有機 可能要請研究生來給您祥解

    敘述=通常有兩個以上(同樣)的官能基,不想要讓其中一個參與反應的話,都會先把他反應成一種可以再被反應回來的形態,就叫保護基

    (A)什麼compound可以用來保護keto?

    答:HO-CH2-CH2-OH

    (B)什麼可以用來保護alcohol?

    答:benzyl-

    答案應該有很多,要看反應,我簡單寫用過的
