The invention discloses a method for synthesizing ph-dicarbonyl-
aryl-formic-
ether series compounds based on the
metal-free participation method, and belongs to the technical field of
organic chemistry. The method includes the steps that phalkynyl benzoic
ether is used as a reaction substrate,
bromide is added to serve as a
bromine source, peroxosulfuric acid inorganic salt serves as an
oxidizing agent, a
solvent is added, the mixture is reacted for 6 hours to 12 hours at the temperature of 60 DEG C to 80 DEG C, then
column chromatography silica gel (SiO2) is added, then the mixture continues to be stirred for 0.5 hour to 1 hour, filtering, extracting and
drying are carried out, filtering is carried out again, filtering liquid is subjected to
pressure reduction distillation, an
organic solvent is removed, then rapid
column chromatography is carried out, and the ph-dicarbonyl-
aryl-formic-
ether series compounds are obtained. By means of a reaction, using of a
metal catalyst is avoided, the reaction condition is mild, the substrate is wide in applicability, easy and convenient to operate, low in cost, small in
by product, high in product purity, convenient to separate and purify and capable of suiting for large-scale preparing.
