Dinitrobenzenesulfonyl Chloride

Reagent 1 can also be converted to an ethylene transfer reagent by condensation with benzonitrile, followed by reduction of the ketosulfoximine and dehydration (eq 6). The resulting S-vinyl-AAtosylsulfoximine reacts with stabilized anions to give cyclopropanes.The W tosyl group in A tosylsulfoximines can be cleaved reductively using sodium anthracenide.  [Pg.240]

Anderson [25] determined the distribution of olefinic bonds in elastomers after derivitization with 2,4-dinitrobenzenesulfonyl chloride using a gel permeation chromatograph equipped with a photometer operating at 254 nm. It is also possible to determine olefinic linkages with a preliminary epoxidation, followed by a method to analyze for the epoxy [26],... [Pg.165]
