Bis(phosphine)cobalt Dialkyl Complexes for Directed Catalytic Alkene Hydrogenation was written by Friedfeld, Max R.;Margulieux, Grant W.;Schaefer, Brian A.;Chirik, Paul J.. And the article was included in Journal of the American Chemical Society in 2014.Application In Synthesis of 2-Isopropylpyridine This article mentions the following:

Planar, low-spin cobalt(II) dialkyl complexes bearing bidentate phosphine ligands, (P-P)Co(CH₂SiMe₃)₂, are active for the hydrogenation of geminal and 1,2-disubstituted alkenes. Hydrogenation of more hindered internal and endocyclic trisubstituted alkenes was achieved through hydroxyl group. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4Application In Synthesis of 2-Isopropylpyridine).

2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Application In Synthesis of 2-Isopropylpyridine

A simple approach for assessment of the corrosion inhibition efficiency of triazole, oxadiazole and thiadiazole derivatives as a function of their concentrations without using complex computer codes was written by Shirazi, Zeinab;Keshavarz, Mohammad Hossein;Esmaeilpour, Karim;Golikand, Ahmad Nozad. And the article was included in Protection of Metals and Physical Chemistry of Surfaces in 2017.SDS of cas: 15420-02-7 This article mentions the following:

A new approach is introduced to predict the corrosion inhibition efficiency of triazole, oxadiazole and thiadiazole derivatives In contrast to the available predictive methods, there is no need to use complex computer codes and unusual complicated mol. descriptors. The new method is based on the number of carbon, hydrogen and nitrogen atoms as well as the contribution of some effective structural parameters in the corrosion inhibition efficiency. The effect of concentration of inhibitors is inserted in the new model to predict the corrosion inhibition efficiency of a desired triazole, oxadiazole and thiadiazole derivative as a function of its concentration For 19 compounds of these derivatives, where the computed results of four complex quantum mech. models were available, the root mean squared (RMS) deviations of the new method is 3.23, which is lower than the computed outputs of four models. High reliability of the new method is also tested for further several compounds In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7SDS of cas: 15420-02-7).

2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. Pyridine has a conjugated system of six 闂?electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H闂佹椿浜滈妴鍗l criteria for aromatic systems. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.SDS of cas: 15420-02-7
