The Schiff‐base condensation of salicylaldehyde and 4‐aminobutanehydrazide hydrochloride leads to the hydrazone‐based ligand H₂salhyab containing an amino side chain. The reaction of H₂salhyab ⋅ HCl with bis(acetylacetonato)dioxidomolybdenum leads to the formation of [MoO₂(salhycab)(MeOH)] (H₂salhycab=2‐((pyrrolidine‐2‐ylidenehydrazineylidene)methyl)phenol), whereby the amino side chain reacted with the hydrazide carbonyl group to form a cyclic amidine with a pyrrolidine ring leading a new type of tridentate hydrazone ligand with [NNO] donor set. X‐ray crystallography revealed the additional coordination of a methanol molecule at the molybdenum(VI) center which leads to the formation of hydrogen‐bonded dimers of the neutral complex in the crystal structure. The complex [MoO₂(salhycab)(MeOH)] was found to be an efficient catalyst for the peroxidic oxidation of phenyl methyl sulfide.

dra基配体与吡咯烷供体及其钼（VI）配合物：合成，结构和反应性。

水杨醛与4-氨基丁烷酰肼盐酸盐的席夫碱缩合反应会生成基于containing的配体H ₂ salhyab，其中含有氨基侧链。H ₂ salhyab⋅HCl与双（乙酰丙酮基）二氧化钼的反应导致形成[MoO ₂（salhycab）（MeOH）]（H ₂salhycab = 2-（（吡咯烷-2-亚苄肼基亚甲基）甲基）苯酚），其中氨基侧链与酰肼羰基反应形成带有吡咯烷环的环状cyclic，从而导致一种新型的具有[NNO]供体的三齿配体放。X射线晶体学分析显示，在钼（VI）中心有一个甲醇分子的额外配位，这导致在晶体结构中形成中性配合物的氢键结合的二聚体。发现络合物[MoO ₂（salhycab）（MeOH）]是用于苯甲基硫醚过氧化氧化的有效催化剂。
