Synthetic Methods and Reactions. VII1. Preparation of Alkyl and Haloalkyl Fluorosulfates from Alkenes (Haloalkenes) or Cyclopropanes with Fluorosulfuric Acid
NN-Dimethylsulphamate esters react with methyl fluorosulphate to give trimethylammoniosulphateesters; the phenyl ester (2) is readily characterized, but alkyl esters immediately give fluorosulphate esters or elimination products, showing that trimethylammonio-sulphate is a very powerful leaving group.
NN -Dimethylsulphamate酯用甲基fluorosulphate得到trimethylammoniosulphate酯反应; 苯基酯(2)易于表征,但是烷基酯会立即生成氟代硫酸酯或消除产物,表明三甲基硫酸铵是一个非常强大的离去基团。
Aromatic substitution. XXXVI. Aluminum trichloride and antimony pentafluoride catalyzed Friedel-Crafts alkylation of benzene and toluene with esters and haloesters
