Cao, Jing published the artcileOrganocatalytic Oxidative Amidation of Aldehydes with Tetrazoles to Construct 2,5-Diaryl 1,3,4-Oxadiazoles, Recommanded Product: 5-(4-(Trifluoromethyl)phenyl)-1H-tetrazole, the publication is Chinese Journal of Chemistry (2015), 33(11), 1239-1243, database is CAplus.
A practical and metal-free oxidative amidation of aldehydes with tetrazoles into 1,3,4-oxadiazoles was developed by employing tetrabutylammonium iodide (TBAI) as catalyst and tert-Bu hydroperoxide (TBHP) as oxidant. A wide range of 2,5-disubstituted 1,3,4-oxadiazoles was conveniently generated in moderate to good yields. Gram-scale reaction was also realized in this catalytic system.
