将异戊二烯通入溴水中可能发生的反应方程式

Answer 1

1,2加成:

CH2C(CH3)CHCH2+Br2==CH2BrCBr(CH3)CHCH2

也有可能与溴水中的次溴酸加成:

CH2C(CH3)CHCH2+HOBr==CH2(OH)CBr(CH3)CHCH2

CH2C(CH3)CHCH2+HOBr==CH2BrC(OH)(CH3)CHCH2

3,4加成:

CH2C(CH3)CHCH2+Br2==CH2C(CH3)CHBrCH2Br

1,4加成:

CH2C(CH3)CHCH2+Br2==CH2BrC(CH3)CHCH2Br

与次溴酸加成:

CH2C(CH3)CHCH2+HOBr==CH2BrC(CH3)CHCH2(OH)

CH2C(CH3)CHCH2+HOBr==CH2(OH)C(CH3)CHCH2Br

彻底加成：

CH2C(CH3)CHCH2+2Br2==CH2BrCBr(CH3)CHBrCH2Br

与次溴酸加成:

CH2C(CH3)CHCH2+2HOBr==CH2BrCBr(CH3)CH(OH)CH2(OH)

CH2C(CH3)CHCH2+2HOBr==CH2BrC(OH)(CH3)CHBrCH2(OH)

CH2C(CH3)CHCH2+2HOBr==CH2BrC(OH)(CH3)CH(OH)CH2Br

CH2C(CH3)CHCH2+2HOBr==CH2(OH)CBr(CH3)CHBrCH2(OH)

CH2C(CH3)CHCH2+2HOBr==CH2(OH)CBr(CH3)CH(OH)CH2Br

CH2C(CH3)CHCH2+2HOBr==CH2(OH)C(OH)(CH3)CHBrCH2Br

其中,与溴的加成占绝对优势,与次溴酸的加成较少.
