One of the main source of demise during the next ten years will be coronary heart disease and stroke, which are brought on by smoking (nicotine). To identify the percentage (%) of nicotine consumption by electrocatalytic sensor towards nicotine for target-specific prevent stroke, four uninuclear Ni complexes of substituted butanimidamide Schiff base ligands [HL] was prepared. All the complexes were thoroughly analyzed by using several spectroscopic techniques such as CHNS analysis, FT-IR, NMR (H & C) UV-Vis and NMR. The analyses showed tetradentate binding mode of ligand around nickel(II) metal ion leads to the structure of square planar with NX (X = O, S) donor fashion. In addition, the well-defined nickel(II) complexes were utilized for oxidation of various alcohols such as cyclohexanol, and benzyl alcohol were produced to the assorted oxidized products with high yield respectively using greener co-oxidant (molecular oxygen). In addition, Nickel(II) complexes was further utilized as catalyst for aryl-aryl coupling reaction Suzuki-Mayura method to obtain biphenyl compound. Furthermore, nickel(II) complexes were exploited for electrochemical detection of nicotine sensing in μM concentration.
未来十年主要的死亡原因之一将是由吸烟（尼古丁）导致的冠心病和中风。为了通过电催化传感器确定针对特定目标预防中风的尼古丁消耗量百分比（%），制备了四种取代丁酰胺席夫碱配体[HL]的单核镍配合物。所有配合物都通过多种光谱技术进行了全面分析，如CHNS分析、傅里叶变换红外光谱（FT-IR）、核磁共振（H和C）、紫外可见光谱（UV-Vis）和核磁共振。分析表明，配体在镍（II）金属离子周围的四齿配位模式导致了具有NX（X = O，S）供体方式的平面正方形结构。此外，定义明确的镍（II）配合物被用于氧化各种醇类，如环己醇，并且分别使用更环保的共氧化剂（分子氧）以高产率将苄醇氧化为各种氧化产物。此外，镍（II）配合物还进一步用作芳基-芳基偶联反应（铃木-真浦方法）的催化剂以获得联苯化合物。此外，镍（II）配合物被用于检测微摩尔浓度的尼古丁传感。
