Abstract A new and useful procedure for the synthesis of sulfinyl chlorides is described involving a combined action of trimethylsilyl acetate and sulfuryl chloride as a oxidative chlorination system on sulfenylderivatives.
By visible-light photoredox catalysis with copper complexes, sulfoximidoyl chlorides add to terminal aryl alkynes to give the corresponding (E)-β-chlorovinyl sulfoximines with exclusive regio- and stereoselectivities in high yields. Two representative products have been characterized by X-ray crystal structure analysis. Radicals appear to be decisive intermediates. As demonstrated by two subsequent
The reaction of sulfinyl chlorides with (l)-N-methylephedrine alone or in the presence of tertiary amines was found to produce diastereomeric sulfinates with diastereomeric purities up to 90%. The diastereomeric ratio is strongly influenced by the nature of substituents on the sulfinyl chlorides and to some extent by the reaction conditions. In a few cases, the pure diastereomers were isolated by chromatography
