with the phosphonate function at the C-4 and C-7 positions. Different alkyl chains were also introduced at the C-2 position to functionalize these two regioisomers and increase their complexation properties. The formation of coordination complexes of selected benzoxazoles with M2+ and M3+ metal cations has been screened in solution using HRMS (high-resolution mass spectrometry) as the analytical tool

金属配合物
配体的良好候选物。合成了两种区域异构体,在 C-4 和 C-7 位置具有
膦酸酯官能团。还在 C-2 位置引入了不同的烷基链,以官能化这两种区域异构体并增加它们的络合特性。使用 HRMS(高分辨率质谱)作为分析工具,已在溶液中筛选了选定的
