- Betylates. 4. The synthesis and preparative nucleophilic substitution reactions of alkyl S-betylates
-
Alkyl S-betylates (S,S-dialkyl-S-3propylsulfonium salts), the first examples of S-betylates (sulfonioalkanesulfonic esters), have been synthesized by two routes, and their suitability as intermediates in the transformation of alcohols by nucleophilic substitution reactions examined.They have been found to react readily in stoichiometric phase transfer processes, including substrate-reagent ion-pair reactions, like their previously studied nitrogen analogues, with the following particular features: (a) they may be used with basic nucleophiles (unlike betylates), (b) they are more simply made from commercially available starting materials than betylates, and (c) they can be made by a route that avoids a final alkylation step.

- OXIDATION OF N-ALKYL-N'-TOSYLHYDRAZINES WITH Hg(OAc)2. A NEW SYNTHESIS OF ETHERS
-
N-Alkyl-N'-tosylhydrazines with Hg(OAc)2 in the presence of alcohols or phenol give high yields of corresponding ethers.Reactions in the presence of acetic acid are also examined.
