A mild and convenient oxidativetransformation of secondaryalcohols to 1,5‐disubstituted tetrazoles is uncovered by employing trimethylsilyl azide (TMSN3) as a nitrogen source in the presence of a catalytic amount of copper(II) perchlorate hexahydrate [Cu(ClO4)2.6 H2O] (5 mol%) and 2,3‐dichloro‐5,6‐dicyano‐para‐benzoquinone (DDQ) (1.2 equiv.) as an oxidant. This reaction is performed under ambient

From simple beginnings: A novel Cu‐promoted direct incorporation of nitrogen into simple hydrocarbon molecules under mild and neutral reaction conditions is described. 1,5‐Disubstituted tetrazoles are efficiently constructed by two CH and one CCbondcleavages (see scheme; TMS=trimethylsilyl). This protocol provides a new and unique strategy to functionalize simple and readily available hydrocarbon
