is methyl, ethyl, isopropyl, n-butyl, n-propyl, n-pentyl, n-octyl, n-tetradecyl, sec-butyl, 3-pentyl, cyclopentyl or benzyl. The diaminoguanidine compounds significantly improve the productivity of ducks if they are fed with the diaminoguanidine compounds. Productivity of pigs or chickens is also improved with such diaminoguanidine compounds.

Different synthetic approaches to functionally substituted benzylamines were examined: reductive amination of alkyl aryl ketones and reduction of aromatic aldehyde oximes. The most efficient procedures were used to prepare a series of previously unknown hydroxy-, alkoxy-, and halogen-substituted benzylamines.
6-triisopropylphenyl) disulfide, an inexpensive reagent with relatively low oxidative ability, as a photo and hydrogen atom transfer catalyst to achieve intramolecular hydroamination. The mechanistic studies as well as the DFT calculations are consistent with a novel process involving N-centered radical generation through the homolysis of the in situ formed N–S species and subsequent cyclization.

烯烃的光诱导反马尔可夫尼科夫加氢胺化通常需要具有高氧化能力的光催化剂来引发单电子过程。在此,我们交替使用双(2,4,6-三异丙基苯基)二硫化物,一种氧化能力相对较低的廉价试剂,作为光和氢原子转移催化剂来实现分子内加氢胺化。机理研究以及 DFT 计算与涉及通过原位形成的 N-S 物种均裂和随后的环化产生 N 中心自由基的新过程一致。可以获得一系列不同的含氮循环。
Alkoxy/halostyryl benzoic acids: Synthesis, crystal structure, and study of mesomorphic and photophysical properties
Alkoxy/halostyrylbenzoic acids were synthesized and evaluated for their mesomorphic and photophysical properties. The trans geometry of the molecules was established by the presence of large coupling constants in H-1-NMR spectra and confirmed further by X-ray diffraction (XRD) analysis of two of the compounds. The straight-chain acids were found fairly stable showing first sign of decomposition above 290 degrees C. The enantiotropic mesophases could only be studied in acids with seven or more methylene groups in the alkoxy chain. Textures of nematic and smectic phases were exhibited by these acids under polarizing optical microscope. Photophysical behavior of the compounds in solution was also investigated.
