    摘要: A process for the preparation of vinyl carbamates of formula I ##STR1## is described which comprises heating an .alpha.-halogeno-carbamate of formula II ##STR2## in which X is a halogen atom at a temperature between 70.degree. and 250.degree. C. for a period of time between several minutes up to several hours. R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are the same or different. The process is applicable to a great variety of products in which R.sub.1, R.sub.2, R.sub.3, and R.sub.4 have different meanings. The process permits to prepare in a simple and economical fashion, vinyl carbamates, which have industrial value and novel vinyl carbamates.

    摘要: An improved process for the dealkylation of alkyl aryl ethers to aryl phenols is provided. In this process, an alkyl aryl ether, such as a methyl ether of an opioid, is contacted with an aqueous acid selected from HBr, HCl, or HI which contains at least one equivalent weight, based on the ether, of boric acid or an inorganic salt of a metal selected from Li, Na, K, Al, Mg, Ca, Mn and Ni. MgBr.sub.2 in aqueous HBr is preferred in dealkylating an N-substituted 14-hydroxydihydronorcodeine.
