In 2019,Green Chemistry included an article by Yamada, Makito; Shio, Yasunori; Akiyama, Toshiki; Honma, Tetsuo; Ohki, Yuuta; Takahashi, Naoyuki; Murai, Kenichi; Arisawa, Mitsuhiro. Computed Properties of C5H6BNO2. The article was titled 《Ligand-free Suzuki-Miyaura coupling reaction of aryl chlorides using a continuous irradiation type microwave and a palladium nanoparticle catalyst: effect of a co-existing solid》. The information in the text is summarized as follows:
The effect of a co-existing metal in the ligand-free Suzuki-Miyaura coupling reaction of aryl chlorides ArCl (Ar = Ph, pyridin-2-yl, naphthalen-1-yl, etc.) is promoted by a ”continuous irradiation type microwave” and a ”palladium nanoparticle catalyst”, and it is found that the co-existing metal affects this reaction due to its absorption ability of microwave energy in the reaction system. It is also observed that spiking occurred more frequently in the presence of a co-existing metal. In the part of experimental materials, we found many familiar compounds, such as 2-Pyridinylboronic acid(cas: 197958-29-5Computed Properties of C5H6BNO2)
2-Pyridinylboronic acid(cas: 197958-29-5) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Computed Properties of C5H6BNO2
