nCH2=CHCH3 + nO2 → [CH2CH(CH3)O]n

[CH2CH(CH3)O]n + H2 → nCH2=CHCH3 + nH2O

R-COOH + R'-OH → R-COOR' + H2O

R-X + Mg → R-MgX

Ar-B(OH)2 + R'-X → Ar-R' + B(OH)2-X

R2C=CR2 + H2 → R2CH-CH2R2

Ph3P=CHR + C=O → Ph3P=CH-CR=O

Ar-X + 2 R-NH2 → Ar-NH2 + R-NH-R

R-OH + R'-OH + 酸催化剂 → R-O-R' + H2O

R-OH + R'-COOH → R-COOR' + H2O
