SuFEx-based synthesis of polysulfates

High-molecular-weight polysulfates are readily formed from aromatic bis(silyl ethers) and bis(fluorosulfates) in the presence of a base catalyst. The reaction is fast and proceeds well under neat conditions or in solvents, such as dimethyl formamide or N-methylpyrrolidone, to provide the desired polymers in nearly quantitative yield. These polymers are more resistant to chemical degradation than their polycarbonate analogues and exhibit excellent mechanical, optical, and oxygen-barrier properties.

Betylates. 1. Synthesis and reactions of an isolable betylate, N,N-dimethyl-N-(phenoxysulfonyl)methanaminium fluorosulfate

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.
