Fungicidal N-substituted ethylendiamino-dithiocarbamates which do not
摘要:
本发明公开了新的具有杀菌活性的N-取代乙二胺二硫代氨基甲酸盐,特别是对Plasmopara viticola感染(B. et C.)Berl. et de Toni(葡萄的Peronoapora)以及对其他对有用农业栽培有害的真菌感染具有活性的这种二硫代氨基甲酸盐。本发明新的具有杀菌活性的二硫代氨基甲酸盐的一个重要特点是使用它们不会导致乙硫氨酰基的形成。
摘要 通过水热法制备了Zn 1-a Fe 2+a O 4+δ (ZFO) 和Mn 1+b Fe 2-b O 4-δ (MFO) 纳米颗粒(NPs)。样品结晶为立方尖晶石结构,属于 Fd 3 ¯ m 空间群。它们的磁特性与其他工作获得的磁特性有很大不同,例如 ZFO NPs 的饱和磁化强度 (Ms) 值为 80.5emu/g,MFO NPs 为 30.7emu/g(在 300K)。使用能量色散 X 射线光谱 (EDS),推导出样品分子式为 ZFO NP 的 Zn 0.30 Fe 2.70 O 4.14 和 MFO NP 的 Mn 1.12 Fe 1.88 O 3.74。拉曼散射 (RS) 光谱表明我们的样品是混合尖晶石铁氧体,而 X 射线吸收光谱 (XAS) 证明样品中的锰和铁具有混合价。RS 和 XAS 以及 XAS 数据的傅立叶变换 (FT) 分析揭示了 ZFO NP 和 M 的 Z n
Process for preparing purified citalopram or one of its salts that comprises the purification of citalopram by selective extractions of citalopram or of its impurities with organic solvents and water under specific conditions of pH and temperature. The crude citalopram can be prepared by a process that comprises reacting 1-[3-(dimethylamine)propyl]-1-(4-fluorophenyl)-1,3-dihydro-5-bromoisobenzofuran with copper cyanide.
It is described a process for preparing, in high yields and purity and without the need of carrying out several steps and/or isolating many intermediates which could lead to undesired by-products, a distamycin derivative of formula

wherein R is a bromine or chlorine atom; or a pharmaceutically acceptable salt thereof. The compounds of formula (I) are useful in therapy as antitumor agents.
A tetrahydrofuran-compound is disclosed herein which is represented by the formula (1) ##STR1## wherein each of X.sub.1 and X.sub.2 is a hydrogen atom or a methyl group, Y is a hydrogen atom or a carbonyl group substituted by a lower alkyl group (Y') having 1 to 4 carbon atoms, i.e., an acyl group (--COY'), and n is 2 or 3, and an insecticide containing the tetrahydrofuran-compound as an effective component.

There are disclosed new fungicidally active N-substituted ethylendiamino-dithiocarbamates, in particular such dithiocarbamates which are active against Plasmopara viticola infections (B. et C.) Berl. et de Toni (Peronoapora of the vine) and against infections by other fungi that are noxious to useful agricultural cultivations. An important characteristic of the new fungicidally active dithiocarbamates of the invention is that use thereof does not result in the formation of ethylenthiourea.
