Abstract:3-(Trimethylsilyl)propynoyl chloride is an important intermediate in the synthesis of silthiopham, a fungicide used to control wheat take-all diseases. Propargyl alcohol (2) was used as the raw material that first went through a silanization reaction, which was then followed by a exchange reaction with grignard reagent to prepare 4. The target compound 1 in purity of 98%(GC) and overall yield of 78% was synthesized by oxidation reaction and chlorination reaction form 4, and the structure of the product was characterized by 1H NMR, 13C NMR and MS spectra. The advantages of the present procedure include mild reaction condition, satisfactory yields and easy operation. Therefore it may be promising for industrial application.
Key words:3-(trimethylsilyl)propynoyl chloride; silthiopham; optimization; synthesis
