Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 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, Quality Control of N-(9-Fluorenylmethoxycarbonyloxy)succinimide.
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. Quality Control of N-(9-Fluorenylmethoxycarbonyloxy)succinimide.
