the hexavalent sulphur atom, hinders all these processes, whereas electron withdrawal facilitates them. Because of this consistency we regard the key process around which this present work was constructed (the trans-sulphamoylation reaction) as being best interpreted in terms of direct nucleophilicattack at sulphur (VI) in the protonated sulphamide, most probably by the para-aryl carbon site in the aromatic
