Quality Control of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, is researched, Molecular C16H21O3P, CAS is 97739-46-3, about Synthesis of Dibenzo[b,f][1,4]oxazepin-11(10H)-ones via Intramolecular Cyclocarbonylation Reactions Using PdI2/Cytop 292 as the Catalytic System. Author is Yang, Qian; Cao, Hong; Robertson, Al; Alper, Howard.
The intramol. cyclocarbonylation of substituted 2-(2-iodophenoxy)anilines, e.g. I, was catalyzed by PdI2 and 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phospha-adamantane (Cytop 292) in an efficient manner. A series of substituted dibenzo[b,f][1,4]oxazepin-11(10H)-ones, e.g. II, were prepared in good yields under mild reaction conditions.
Compound(97739-46-3)Quality Control of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane), if you are interested, you can check out my other related articles.
