4,4'-Oxybis(benzoyl Chloride) synthesis

3synthesis methods
4,4-Chloroformyl phenyl ether can be used as an intermediate in pharmaceutical synthesis and mainly in laboratory research and development.  The toluene solution of 4,4′-Oxybis(benzoic acid) and DMF   were slowly added dropwise with thionyl chloride and stirred for 4h at 70 ℃.  After the reaction was completed, it was concentrated to dryness to obtain a brown solid intermediate product, 4,4-chloroformyl phenyl ether.

Yield:7158-32-9 95%

Reaction Conditions:

with thionyl chloride in N,N-dimethyl-formamide;toluene at 95; for 3 h;

Steps:

Synthesis of Acid Chloride Product (A)
4,4'-diphenyl ether dicarboxylic acid 25.3 g (0.096 mol), 0.85 g (0.012 mol) of dimethylformamide and 80 ml of toluene was prepared. For the first mixed solution in the stirring state, 58.4 g (0.46 mol) of thionyl chloride, And 20 ml of toluene Was gradually added dropwise at room temperature. After completion of the dropwise addition, the liquid obtained was heated to 95 ° C., It was refluxed for 3 h. Then, by allowing the yellow transparent liquid obtained after heating / refluxing to cool, It has the following molecular structure 4,4'-diphenyl ether dicarboxylic acid chloride (Hereinafter referred to as "acid chloride (A)" In some cases) as a toluene solution. further, The toluene solution was applied to a rotary evaporator, and toluene, Thionyl chloride and hydrogen chloride were removed, 4,4'- Diphenyl ether dicarboxylic acid chloride solid 26.9 g (0.091 mol, 95% yield) Was obtained.
