A asymmetric to P for the preparation of compounds (by machine translation)

The present invention discloses a non-symmetrical P-composition preparation method, in order to backward and halogenated aromatic hydrocarbons as raw material, solid alkali catalyst in dichloromethane in a two-phase system to conduct the condensation reaction, to obtain the asymmetric double-substituted jingjing passes through catalytic oxidation, to prepare the asymmetric P-compound. For the method of the invention the product yield is greater than 85% and above, the purity of the product reach 98% and above. The invention compared with the prior art, safe and convenient operation, the operating environment is greatly improved, avoiding the danger in operation of the diazotization step. The invention mild reaction conditions, good selectivity, process is easy to control, the un-reacted organic raw materials can be recycled, thereby greatly reducing the environmental protection COD treatment intensity, the product quality is stable, it is suitable for industrial production.

Convenient reduction of azobenzenes and azoxybenzenes to hydrazobenzenes by sodium dithionite using dioctylviologen as an electron transfer catalyst

Various ezobenzenes and azoxybenzenes were reduced almost quantitatively to the corresponding hydrazobenzenes as sodium dithionite under mild conditions without the formation of aniline derivatives, using dioctyl viologen as an electron-transfer catalyst in acetonitrile-water.
