A series of 1,3,5-trisubstituted 1,2,4-triazoles were synthesized via the intermolecular cyclization of hydrazonyl chlorides with nitriles catalyzed by ytterbium triflate [Yb(OTf)3]. The amount of catalysis was discussed and Yb(OTf)3 could be reused without loss of activity. Copyright Taylor & Francis, Inc.
