Method for preparing substituted mixed alkynyl ethers

   
   

The present invention relates to a process for preparing mixed substituted alkynyl ethers. More particularly, the invention concerns the preparation of mixed ethers derived from a benzyl type alcohol and a substituted alkynyl alcohol. The process of the invention for preparing a benzyl/substituted alkynyl type mixed ether is prepared from a benzyl/alkynyl type mixed ether with a hydrogen atom on the triple bond is characterized in that it consists of reacting a mixed ether derived from a benzyl type alcohol and an alkynyl alcohol with a hydrogen atom on the triple bond with an alkylation agent, in the presence of an anionisation agent.

A invenção atual relaciona-se a um processo para preparar ethers substituídos misturados do alkynyl. Mais particularmente, a invenção concerne a preparação dos ethers misturados derivados de um tipo benzyl álcool e um álcool substituído do alkynyl. O processo da invenção para preparar um tipo ether misturado do alkynyl de benzyl/substituted é preparado de um tipo ether misturado de benzyl/alkynyl com um átomo do hidrogênio na ligação tripla é caracterizado que consiste reagir um ether misturado derivado de um tipo benzyl álcool e um álcool do alkynyl com um átomo do hidrogênio na ligação tripla com um agente do alkylation, na presença de um agente do anionisation.
