Kinetics of the reaction of diphenylphosphinic hydrazide with phenyl isothiocyanate in the presence of benzopyridines was written by Yanchuk, N. I.. And the article was included in Zhurnal Obshchei Khimii in 1986.Application of 644-98-4 This article mentions the following:
The catalytic activity of pyridines and benzopyridines in the reaction of Ph2P(O)NHNH2 with PhNCS to give Ph2P(O)NHNHCSNHPh decreased in the following order: isoquinoline > pyridine > 2,4-dimethypyridine > 2,4,6-trimethylpyrdine > 2-ethylpyridine > 2-picoline > quinoline > 2-isopropylpyridine > acridine > 2,6-dimethylpyridine > quinaldine. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4Application of 644-98-4).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Application of 644-98-4
