The cyano substitution reaction is an important method for introducing cyano functional groups in organic synthesis. In this paper, a series of cyano compounds were synthesized by nucleophilic substitution reaction using acetone cyanohydrin as cyanation reagent and aliphatic haloalkanes R—X (X=Cl, Br, I) as substrates. The results show that the cyanation product can be obtained by reacting the acetone cyanohydrin with the corresponding halogenated alkanes at 50 ℃, and the yield can reach 70%~99%. The reaction solvent is the mixture of tetrahydrofuran (THF) and 1,3-dime- thylimidazolinone (DMI) (volume ratio of 3:1), and the base is LiOH?H2O. This reaction uses cheap and low toxicity acetone cyanohydrin instead of highly toxic sodium cyanide or other expensive cyanide reagents requiring harsh conditions and it also does not require precious metals as catalysts. The reaction conditions is mild so that it has extensive application and great value of practical application.
