Luo et al. Keywords Decomposition N-Tosylhydrazones Cs CO Azines 2 3 Introduction Azines, N–N linked diimines, which exhibit interesting biological [1–3], conductive [4–6], and optical [7–9] properties and are extensively used as synthetic intermediates [10–14], have received increasing attention in recent years. Generally, azines are prepared by the condensation of aldehydes or ketones with hydrazine hydrate in solution under refluxing conditions or with promoters such as iodine or acid [15–17]. These reactions proceed rapidly but often generate large amounts of unwanted byproducts. Very recently, Peltier et al. [18] reported the first examples
