由乙酰乙酸乙酯和乙二醇怎么合成CH3COC(CH3)3

(1)合成乙酰乙酸乙酯:C2H5OCOCOOC2H5

水解------CH3CH2OH

+

HOCOCOOH;

CH3CH2OH

(KMnO4/H+)----CH3COOH,

CH3CH2OH+CH3COOH(浓硫酸加热酯化)-----CH3COOC2H5(加C2H5ONa)-----

CH3COCH2COOCH2CH3.

(2)合成2-丁烯:

C2H5OCOCOOC2H5

---(加NaBH4)---CH2OHCH2OH

(加PCl3)

----CH2ClCH2Cl

(醇/NaOH)

----CH≡CH

（加Na）----NaC≡CNa

(加CH3Cl)---CH3C≡CCH3(控制氢化Ni/H2)---CH3CH=CHCH3

(3)合成3-甲氧基-2-氯丁烷:

CH3CH=CHCH3

+

(Ag/O2)----CH3CHoCHCH3(2,3-环氧丁烷)----(加CH3OH)

----

CH3CHOHCH(OCH3)CH3

-------

(加PCl3)-----CH3CHClCH(OCH3)CH3

(4)合成产物:

CH3COCH2COOCH2CH3

+

C2H5ONa/

CH3CHClCH(OCH3)CH3

-----

CH3COCH(COOCH2CH3)CH(CH3)CH(OCH3)CH3

+NaCl(这步在这儿无法完全表达,你自己画出来)----加稀NaOH/H2O酮式分解得---CH3COCH2CH(CH3)CH(OCH3)CH3

------(加(1)CH3MgCl/(2)H3O+)---(

CH3)2COHCH2CH(CH3)CH(OCH3)CH3

(加HI)

--------(

CH3)2COHCH2CH(CH3)CHOHCH3(产物), 0
