In 2019,Tetrahedron Letters included an article by Sun, Song; Zhou, Cong; Cheng, Jiang. COA of Formula: C33H24IrN3. The article was titled 《Synthesis of 4-cyanoethylated benzoxazines by visible-light-promoted radical oxycyanomethylation of olefinic amides with bromoacetonitrile》. The information in the text is summarized as follows:
A facile and efficient protocol for the visible-light-promoted radical oxycyanomethylation of olefinic amides 2-R1C(O)NHC6H4C(=CH2)R2 (R1 = Me, Ph, naphthalen-1-yl, cyclohexyl, thiophen-2-yl, etc.; R2 = Me, phenyl) with bromoacetonitrile has been developed, affording a series of 4-cyanoethylated benzoxazine derivatives I in moderate to excellent yields. The reaction featured with diverse functional group tolerance and mild reaction conditions. The experimental part of the paper was very detailed, including the reaction process of fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6COA of Formula: C33H24IrN3)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) 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.COA of Formula: C33H24IrN3
