| titleOfInvention | A kind of microwave quickly prepares seven yuan of methods of lactone of biaryl |
| abstract | Seven yuan of methods of lactone of biaryl are quickly prepared the invention provides a kind of microwave, it comprises the following steps：Step A：With compound 1 as reactant, with dissolved oxygen acetonitrile as solvent, with N heterocycle carbines as catalyst, there is pole reversal reaction under the microwave of 700 900W and in 25 80 DEG C of environment, obtain crude product, step B：Seven yuan of lactones of biaryl are extracted from the crude product；That is compound 2.The reaction equation of above-mentioned reaction is： R, R ' separately selected from the one kind in following：Halogen, nitro, methyl, methoxyl group and phenyl ring have two phenyl of common carbon atom；X is halogen.The present invention can obtain seven yuan of lactones of biaryl that yield is more than 85% at most in 60min, and the preparation technology for having reported substantially reduces the reaction time, have the advantages that production efficiency is high, process is simple. |
