Reduction–substitution reactions of pertechnetate with a class of O,P-bidentate phosphinocarboxylic acid ligands HLn[n= 1,2-(diphenylphosphino)benzoic acid; n= 2, 3-(diphenylphosphino)propionic acid; n= 3, (diphenylphosphino)acetic acid; n= 4, 3-(diethylphosphino)propionic acid] afforded a series of neutral and paramagnetic [TcLn3] complexes. The products have been characterized by means of elemental analysis
高tech酸酯与一类O,P-二齿膦酰基羧酸配体HL n的还原-取代反应[ n = 1,2-(二苯基膦基)苯甲酸; n = 2,3-(二苯基膦基)丙酸; n= 3,(二苯基膦基)乙酸;n= 3。n = 4,3-(二乙基膦基)丙酸]提供了一系列中性和顺磁性[TcL n 3 ]配合物。该产品已通过元素分析,IR,1 H NMR,UV / VIS和FAB质谱以及[TcL 2 3 ]的X射线晶体学进行了表征。后者在单斜空间群P 2 1 /中结晶。Ñ与ž = 4,一个= 21.718(10),b = 12.954(6),C ^ = 18.038(9)α和β= 106.59(4)°。最终的R值为0.061。三去质子化螯合物包围金属在采用子午结构的扭曲八面体的环境中,并因此有两对像供体原子的反式与剩余的磷彼此原子的反式与氧原子。利用短寿命同位素99m Tc进行了类似的还原取代反应。所得99m的理化性质Tc标记的物种与使用长寿命同位素99
