合成了1-(2-吡啶甲基)-1,2,4-三唑(L)并研究了其与有机锡和羰基钼(钨)的配位反应,合成了通过三唑4位氮原子以单齿形式配位的有机锡衍生物L2SnR2Cl2(R=Me,n-Bu或Ph)和羰基金属配合物LM(CO)5(M=Mo或W),以及N,N螯合双齿配位的四羰基金属配合物LM(CO)4。当用氯化苄处理L时,制得了相应的三唑盐,该盐用氧化银处理后与M(CO)5THF或M(CO)4(NHC5H10)2(NHC5H10为哌啶)反应,得到了基于三唑的氮杂环卡宾衍生物L′M(CO)5和L′M(CO)4(L′=1-(2-吡啶甲基)-4-苄基-1,2,4-三唑-5-碳烯)。X-射线单晶衍射分析表明,在L′M(CO)5中氮杂环卡宾配体L′表现为通过卡宾碳配位的单齿配体;而在L′M(CO)4中,L′表现为通过卡宾碳和吡啶氮原子配位的螯合[C,N]双齿配体。
Synthesis of 1- (2-picolyl) -1,2,4-triazole (L) and its coordination with organotin and carbonyl molybdenum (Tungsten) The organotin derivatives L2SnR2Cl2 (R = Me, n-Bu or Ph) and the metal carbonyl complexes LM (CO) 5 (M = Mo or W) coordinated in monodentate form and N, N chelated bidentate Tetracarbonyl metal complex LM (CO) 4. When L is treated with benzyl chloride, the corresponding triazolium salt is obtained which is treated with silver oxide and reacted with M (CO) 5THF or M (CO) 4 (NHC5H10) 2 (NHC5H10 is piperidine) to give The triazole-based azacyclic carbene derivatives L’M (CO) 5 and L’M (CO) 4 (L ’= 1- (2- picolyl) Triazole-5-carbene). The X-ray single crystal diffraction analysis showed that the azacyclocarbene ligand L ’appeared to be a monodentate ligand coordinated by carbene carbon in L’M (CO) 5. In L’M (CO) 4, L ’appears as a chelated [C, N] bidentate ligand that coordinates through the carbazole carbon and the pyridine nitrogen atom.
