【Abstract】 2.4.6.-Tribromophenyl acrylate was prepared by a two-step process.Firstly,20 parts of POC13 were added to a mixture of 32 parts of tribromophe-nol and 12 parts of acrylic acid and the mixture was heated for 7 hours at 90℃ to give 98% tribromophenyl-β-chloro-propionate(I).Then 4 parts of (I) were mixed with 6 parts of triethylamine.The mixture was under continued stirring for 1 hour at 110℃％,giving 99% tribromophenyl acrylate.The total yield of these two steps was as high as 90%.更多还原
