Chemistry is traditionally divided into organic and inorganic chemistry. SDS of cas: 52522-40-4, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 52522-40-4
A highly diastereoselective synthesis of trifluoromethyl-substituted indolines under palladium catalysis is disclosed. The reaction proceeds by interceptive decarboxylative benzylic cycloaddition (IDBC) of nonvinyl, trifluoromethyl benzoxazinanones with sulfur ylides. The palladium-pi-benzyl zwitterionic intermediates are suggested for this transformation, and this would be the first example of an IDBC reaction.
