Abstract (en)
[origin: FR2798928A1] The invention concerns a method for preparing substituted mixed alkynyl ethers. More particularly, the invention concerns the preparation of mixed ethers derived from substituted benzyl alcohol and alkynyl alcohol. The inventive method for preparing a substituted mixed benzyl/alkynyl ether from a mixed benzyl/alkynyl ether having a hydrogen atom on the triple bond is characterised in that it consists in reacting a mixed ether derived from a benzyl alcohol and an alkynyl alcohol having a hydrogen atom on the triple bond with an alkylating agent, in the presence of a negative ion chemical ionizing reagent.
