New Advances in Chemical Research, May 2021.Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, nano-ceramics, preparation and modification of special coatings. 82911-69-1, Name is N-(9-Fluorenylmethoxycarbonyloxy)succinimide, belongs to thiazines compound, is a common compound. In a pantent, author is Dong, Jian-Lian, once mentioned the new application about 82911-69-1, SDS of cas: 82911-69-1.
Chemoselective Synthesis of Structurally Diverse 3,4-Dihydroquinazoline-2(1H)-thiones and 4H-Benzo[d][1,3]thiazines
An efficient, mild, and substrate/catalyst-controlled chemoselective reaction of o-isothiocyanato-(E)cinnamaldehyde with amines has been established, producing three types of six-membered heterocycles: 2-(4Hbenzo[d][1,3]thiazin-4-yl)acetaldehydes, 2-(2-thioxo-1,2,3,4-tetrahydroquinazolin-4-yl)acetaldehydes, and (E)-4-(2-methoxyvinyl)-4H-benzo[d] [1,3]thiazines. The reaction scopes were quite broad and excellent yield was achieved. This method is extremely efficient and practical and can be conducted on a gram-scale with slightly inferior reactivity under catalyst-free conditions at low cost, making it an ideal alternative to existing methods.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 82911-69-1 is helpful to your research. SDS of cas: 82911-69-1.
