Im, Jeong Kyun; Yang, ByeongDo; Jeong, Ilju; Choi, Jun-Ho; Chung, Won-jin published the artcile< N-Chlorination-induced, oxidative ring contraction of 1,4-dimethoxyphthalazines>, Name: 5-Chloroisobenzofuran-1,3-dione, the main research area is dimethoxyphthalazine trichloroisocyanuric acid chlorination oxidative ring contraction; chlorophthalimide preparation.
A rarely explored oxidative ring contraction of electron-rich 1,2-diazine was described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that was accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations
Tetrahedron Letters published new progress about Chlorination. 118-45-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H3ClO3, Name: 5-Chloroisobenzofuran-1,3-dione.
