Chemistry is traditionally divided into organic and inorganic chemistry. SDS of cas: 34784-05-9, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 34784-05-9
A highly efficient iodine/TBHP-mediated one-pot deoxygenative and regioselective 2-sulfonylation of quinoline N-oxides with sodium sulfinate salts has been developed. This metal-, base-, and phosphorus-free protocol employs readily accessible and easy-to-handle reagents and can be conveniently carried out at room temperature under mild conditions, providing an alternative access to a series of 2-sulfonylquinolines and other related heteroaryl sulfone products in moderate-to-excellent yields within a short reaction time.
