PROCEDURE

实验过程

A solution of 75.4 g. 5-octyl-2-thiophenecarboxaldehyde and 117.6 g. ethyl (triphenylphosphoranylidene)acetate in 400 ml. tetrahydrofuran is refluxed for 20 hours. The solution is concentrated, the semi-solid residue is slurried with ether and filtered. Concentration followed by distillation of the resultant oil yields ethyl 5-octylthiophene-2-acrylate as an oil.
