In an article, author is Rastogi, Shiva K., once mentioned the application of 5509-65-9, HPLC of Formula: https://www.ambeed.com/products/5509-65-9.html, Name is 2,6-Difluoroaniline, molecular formula is C6H5F2N, molecular weight is 129.11, MDL number is MFCD00007655, category is phthalazine. Now introduce a scientific discovery about this category.
Two protocols for oxygenation of aromatic C-H bonds ortho-positioned to the phthalazine ring were developed. The transannulation of the phthalazine ring to a naphthalene moiety by an Inverse Electron Demand Diels-Alder (IEDDA) reaction led to the synthesis of naphtho[2,1-c]chromenes, 1-(ortho-hydroxyaryl)naphthalenes and 6,7-dihydrobenzo[b]naphtho[1,2-d]oxepine. This new strategy based on the utilization of transformable nitrogen heterocycles in C-H functionalization chemistry can be potentially applicable to the synthesis of a broad range of biaryl compounds.
