relatively broad scope of catalytic oxidation reactions in the liquid phase. Its catalytic behavior may be compared to a reversible mutation, featuring the best sides of homogeneous and heterogeneous catalysis. The original solid material converts into soluble active species, and the latter revert to the original material upon completion of the catalytic reaction, precipitating and allowing straightforward
3-(1,2,4-三唑-4-基)金刚烷-1-羧酸(tradcH),一种杂双功能有机配体,其中羧酸和1,2,4-三唑基通过刚性的1,3相连-金刚烷二烯基间隔基用于合成MoVI氧化物有机杂化物。配体从水中结晶为tradcH·H2O(1),具有二维氢键网络,从乙醇中结晶为环状分子溶剂化物(tradcH)3·2EtOH(2)。在水热条件下用MoO3处理tradcH得到了一种新的三氧化钼杂化物[MoO3(tradcH)]·H2O(3),其结构经过了表征。在图3中,钼原子形成μ2 -O-MoO 2} n的聚合物之字形链,该链由双三唑桥支撑,而羧酸末端未配位。Mo中心的配位环境显示为扭曲的顺式MoN2O4}八面体。该杂化物表现出高的热稳定性(高达270°C),并被用于液相中相对较宽的催化氧化反应范围。可以将其催化行为与可逆突变进行比较,该突变具有均相和异相催化的最佳方面。原始固体物质转化为可溶性活性
