In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of Dibenzo[b,f][1,4]oxazepin-11(10H)-ones via Intramolecular Cyclocarbonylation Reactions Using PdI2/Cytop 292 as the Catalytic System, published in 2010-09-17, which mentions a compound: 97739-46-3, mainly applied to dibenzooxazepinone preparation; phenoxyaniline intramol cyclocarbonylation palladium tetramethylphenyltrioxaphospha adamantane catalyst, Electric Literature of C16H21O3P.
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.
This literature about this compound(97739-46-3)Electric Literature of C16H21O3Phas given us a lot of inspiration, and I hope that the research on this compound(1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane) can be further advanced. Maybe we can get more compounds in a similar way.
