    An I2-promoted, metal-free domino protocol for one-pot synthesis of 1,3,4-oxadiazoles has been developed via oxidative cleavage of C(sp2)–H or C(sp)–H bonds, followed by cyclization and deacylation. In this reaction, the use of K2CO3 as a base is found to be an essential factor in the cyclization and the C–C bond cleavage. This procedure proceeded smoothly in moderate to high yields with good functional

    strategy for the synthesis of 1,3,4-oxadiazoles was established through direct annulation of hydrazides with methyl ketones. It was found that the use of K2CO3 as a base achieves an unexpected and highly efficient C–C bond cleavage. This reaction is proposed to go through oxidative cleavage of Csp3–H bonds, followed by cyclization and deacylation.
