摘要

Oxidation of dihydrazones of α-diketones to acetylene was investigated by using sodium periodate. Further, the described method is also found to be suitable for deprotection of monohydrazones of aldehydes and ketones. The process is mild, efficient, and applicable to both electron-withdrawing and-donating substituents to give good to excellent yields.
