triarylideneacetylacetones with hydrazine hydrate in acetic acid affords an excellent yield of (E)‐s‐trans‐1‐acetyl‐5‐aryl‐3‐styryl‐2‐pyrazolines via decinnamoylation. The structures of these compounds were elucidated using 1H, 13C and two‐dimensional NMR techniques such as H,H‐COSY, C,H‐COSY, NOESY and HMBC. 15N NMR data for these compounds were also obtained and the results are discussed.
