Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials.92-30-8, Name is 2-(Trifluoromethyl)-10H-phenothiazine, belongs to thiazines compound, is a common compound. In a pantent, author is Li, Yuewen, once mentioned the new application about 92-30-8, SDS of cas: 92-30-8.
N-Radical Initiated Aminosulfonylation of Unactivated C(sp(3))-H Bond through Insertion of Sulfur Dioxide
N-Radical initiated aminosulfonylation of unactivated C(sp(3))-H bond through insertion of sulfur dioxide in the presence of visible light is reported. O-Aryl oximes react with DABCO center dot(SO2)(2) smoothly at room temperature under blue LED irradiation without any metals or photoredox catalysts, generating diverse 5,6-dihydro-4H-1,2-thiazine 1,1-dioxides in good yield. Additionally, this approach can be extended to the synthesis of 1H-benzo[d][1,2]thiazine 2,2-dioxides. During the reaction process, an N-radical is initiated by the treatment of O-aryl oximes with DABC center dot(SO2)(2) under visible-light irradiation. It is followed by aminosulfonylation of a nearby C(sp(3)) H bond through 1,5-hydrogen atom transfer with accompanying insertion of sulfur dioxide to provide 1,2-thiazine 1,1-dioxide derivatives.
