Sulfimidation of thio-ether crown systems: the X-ray crystal structure of the {[9-ane]S2S(NH2)}+, {[9-ane]SS(NH2)S(NH2)}2+, and {[9-ane]S(NH2)S2( -N)}2+ cations
Treatment of the thio-ether crown [9-ane]S 3 ( 1 ) with 1 equiv of O-mesitylsulfonylhydroxylamine (MSH) yields the water-soluble protonated sulfimide {[9-ane]S 2 S(NH 2 )} + ( 2 ). Two equiv of MSH leads to the formation of {[9-ane]SS(NH 2 )S(NH 2 )} 2+ ( 3 ), while excess MSH generates the {[9-ane]...
