Clarke, Kenyon and Phillips3 proposed the much more plausible formula, I, in which the sulfur is attached to nitrogen by a coordinate bond; they supported this formula by showing that m-carboxyphenyl-methylsulfin-p-toluenenesulfonylimine (I, R'= m-CsH&OOH, R”= CHI) could be resolved, similar to unsymmetrical sulfoxides and to sulfinic esters. Since these compounds are known to have coordinate links between sulfur and oxygen, the ...
