A novel, high-yielding method for sulfation of alcohols has been developed, proceeding via sulfite- and sulfate diester intermediates. Sulfite diesters serve as versatile sulfate monoester precursors, allowing for transformations that are difficult or impossible with the latter compounds.

New substrates and reaction conditions which may be expected to yield phenyl cation intermediates have been investigated.The approaches used were: (a) solvolysis of PhX in fluorinated alcohols, where X=-N(O)=NOTs (tosyloxyazoxy), -N(O)=NONf (Nf=C4F9SO2su

Phenyl betylate fluorosulfate (2), the first example of a "betylate" (trialkylammoniosulfate ester), has been prepared by methylation of phenyl N,N-dimethylsulfamate with methyl fluorosulfate.Nucleophiles react with 2 either by attack on the sulfur or methyl carbon atoms, but with no sign of any products derived from benzyne or the phenyl cation.A synthesis of enol N,N-dimethylsulfamates has been devised using a reagent, Me2NSO2N(1+)Me3 FSO3(1-), prepared from tetramethylsulfamide and methyl fluorosulfate, but no satisfactory method was found for converting the sulfamic ester to the betylate.Evidence is presented that phenyl chlorosulfate reacts with trimethylamine to give the phenylbetylate which then undergoes further reaction.
