SYNTHESİS OF THE PROPARGYL ESTERS OF β-TRIHALOGENMETHYLPROPANOLS
It has been determined that haloforms (CHCl3, CHBr3), chemo- and regioselectively are added to double bond of allylpropargyl ester in the presence of catalytic amounts of sulphuric acid with forming the propargyl esters of β-trihalogenmethylpropanols. Unlike of chlorine analog the acetylene tribromoester easily is hidrolized by 2% water solution of NaHCO3, transforming into acetylene esteracid
