The preparation and crystal structures of derivatised sulfimidium salts

Abstract

Preparation and protonation of the hydroxy derivatised sulfimides 2- and (4-C₆H₄OH)(Ph)SNH gives a sulfimidium cation with three hydrogen bond donors, two NH hydrogens and an OH hydrogen. These all interact with the chloride counterion to give extended hydrogen bonded arrays. The effect of the position of the hydroxy group on the network produced is investigated. Also reported is the structure of the bis-sulfimidium salt [1,3-(PhSNH₂)₂C₆H₄]Cl₂ which also exhibits a hydrogen bonded array.
