A series of 1,4-diaryl tetrazol-5-ones were synthesized by copper mediated N-arylation of 1-phenyl-1H-tetrazol-5(4H)-one with aryl boronic acids, o-R(1)C(6)H(4)B(OH)(2) where R(1)=H, OMe, Cl, CF(3), Br, CCH. The 1,4-diaryl tetrazol-5-ones substituted with OMe, Cl, CF(3), Br underwent thionation with Lawesson's reagent to yield the corresponding 5-thio derivatives. The 1-(2-bromophenyl)-4-phenyl-1H-tetrazole-5(4H)-thione so obtained was subjected to lithiation/protonation and Sonogashira coupling to produce 1,4-diphenyl-1H-tetrazole-5(4H)-thione and 1-(2-ethynylphenyl)-4-phenyl tetrazole-5-thione, respectively.
