Quinones were firstly used as dipolarophiles in a photoclick 1,3-cycloaddition with 2,5-diaryltetrazoles, as photoactivatable predipoles, providing a novel and efficient access to three types of pyrazole-fused quinones (indazoledione derivatives). Distinc
Efficient synthesis of 2,5-disubstituted tetrazoles via the Cu 2O-catalyzed aerobic oxidative direct cross-coupling of N-H free tetrazoles with boronic acids

We present a new protocol that allows for the synthesis of 2,5-disubstituted tetrazoles via the direct coupling of N-H free tetrazoles and low toxic boronic acids in the presence of only a catalytic amount of Cu 2O (5 mol%) as catalyst and 1 atm of environmentally benign O 2 as oxidant, without the need for other additives. This method represents a simple, green, and atom-efficient synthesis of 2,5-disubstituted tetrazoles. The Royal Society of Chemistry 2012.
Palladium- and copper-catalyzed selective arylation of 5-aryltetrazoles by diaryliodonium salts
Beletskaya, Irina P.,Davydov, Dmitri V.,Gorovoy, Matvey S.

Palladium(0)-catalyzed arylation of 5-aryltetrazoles in t-BuOH at 80°C with diaryliodonium salts proceeds in the presence of copper(II) phenylcyclopropyl carboxylate regioselectively at the N2 position.
