摘要

Abstract An environmentally friendly, efficient method for transforming alkynes into substituted benzenes catalyzed by p-toluenesulfonic acid monohydrate (p-TsOH· H2O) under solvent-free conditions has been developed, which conforms to the principles of “green” chemistry and overcomes the shortcomings of previous methods for the synthesis of substituted benzenes. The reaction is quite general and provides good to excellent yields. ...
