摘要:在h 2 O中由肼衍生物(见图1)和羰基化合物可逆形成而生成的传递系统有效地提高了各种香料应用中挥发性醛和酮(r 1 R 2 Co)的持久性.通常以(e)构型在亚胺双键(nhnc)上获得,对于脂族酰基hydr R'Conhncr 1 R 2(r'=烷基),相对于酰胺而言,其为顺式和反式构象异构体键(conhn).平均自由能垒约为.通过可变温度的1 H-NMR测量确定了78 Kj / Mol的酰胺键旋转(图2).在h 2 O存在下,的形成是完全可逆的,达到了由肼衍生物,羰基化合物和相应的composed组成的平衡.通过uv / Vis光谱进行的动力学测量表明,That的形成和水解达到了相同的平衡.速率常数强烈依赖于ph值,并且随着ph值的降低而增加(表1).肼结构对速率常数的影响不如ph效应那么明显,表面活性剂的存在降低了平衡速率(表1和表2).3).Formation形成的完全可逆性允许通

摘要:Process for the preparation of nitride complexes of transition metals for use as radiopharmaceutical products or for the synthesis of novel pharmaceutical products. The process consists in reacting an oxygenic transition metal compound such as 99m Tc , 186 Re or 188 Re , with a first nitrogenous ligand such as sodium nitride or a nitrogenous compound such as S-methyl, N-methyl dithiocarbazate, and a reducing agent consisting of either tin (II) or a dithionite. The product so obtained can be used for the preparation of radiopharmaceutical products by a reaction with a second ligand such as sodium dithiocarbamate.
