Method of preparation of the carbonates of ethyl bromoacetate - 1 and of hydrocarbons, and new carbonates of ethyl bromoacetate - 1 and of hydrocarbons,

摘要

The invention relates to a method of preparation of the carbonates of ethyl bromoacetate - 1 and of hydrocarbons characterizes in react hydrobromic acid, anhydrous on a vinyl carbonate and of hydrocarbons, of formula: & br / (see appended drawing in bopi) & br / in which r denotes an aliphatic radical at c a c or cycloaliphatic c, a saturated, substituted or not, or an aromatic radical substituted or not, at a temperature ranging between 10 and 100c. / p & & p & the invention also relates to new carbonates of ethyl bromoacetate - 1 and of hydrocarbons, of formula: & br / (see appended drawing in bopi) & br / / p & & p & these carbonates are particularly to the introduction of group carbonate in a molecule.
