Dioximes have special properties as analytical reagents for transition metals. Dioximes complexation properties with metals were carried out by many investigations and these complexations showed a wide range of applications such as antimicrobial and theranostic agents.

2017年6月6日 · A novel dioxime derivative (2E,2′E,3E,3′E)-3,3′-(pyrimidine-4,5-diylbis(azanylylidene))bis(butan-2-one)dioxime was synthesized with a yield of 65%. IR, elemental analysis, mass spectroscopy and 1 H-NMR were used to characterize the structure of the synthesized compound.

2023年9月1日 · The copper(II) complex was prepared by reaction of the ligand with copper(II) perchlorate hexahydrate in methanol under constant stirring for 1 h at room temperature. The newly synthesized dioxime ligand and its Cu(II) complex were characterized by several analytical and spectroscopic methods.

2022年11月2日 · New dioxime derivatives of vitamin B6, compounds 1–7, were prepared in two steps, but the synthesis was attempted in two ways. First, a pyridoxal monooxime was quaternized with 2-bromoacetophenones, and then an attempt was made to convert the carbonyl group between the two aromatic rings into an oxime group.

该品主要用于制造气囊、水胎、电线电缆的绝缘层、耐热垫圈等。 用量1-2份。 与氧化铅10-6份或促进剂DM4-2份配合。 对苯醌二肟是测定镍的试剂。 由苯酚亚硝化生成对亚硝基苯酚，经转位成对醌单肟，再与盐酸羟胺反应得该品。 在搅拌下，慢慢将苯酚溶于30%氢氧化钠溶液，在0℃与亚硝酸钠混合，再加入30%硫酸，使温度保持在7-8℃，搅拌1h。 滤出结晶，用水洗去酸性，得对亚硝基酚。 再经转位，与盐酸羟胺水溶液混合，加热至70℃进行肟化反应。 反应毕，过滤得对 …

2022年10月26日 · Dioxime oxalates, a type of carbonyl oximes, are well-known as clean sources of iminyl radicals that undergo key organic chemistry transformations. A series of dioxime oxalates is reported in this manuscript, obtained by the reaction of the corresponding oximes with oxalyl chloride and Et3N at room temperature.

99mTc-dioxime was radio-synthesized with a high radio-chemical yield of 97.8 ± 0.5% and in vitro stability of 6 h under the optimum conditions. The preclinical evaluation of 99mTc-dioxime in solid tumor-bearing mice showed high accumulation in solid tumor cells with a high Target/Non-Target ratio of 5.14 at 30 min post-injection. This study
