Patent

CA 2513737

A process for the production of ethers, characterized by reacting a conjugated diene with an alcohol via telomerization in the presence of a catalyst composition comprising a palladium compound, an isocyanide represented by the general (I): R1R2R3CNC (I) and a base represented by the general formula (II): M(OR4)n (II) [in the formulae, each symbol is as defined in the description]. According to the process, ethers can be industrially advantageously produced by telomerization of a conjugated diene with an alcohol.

L'invention concerne un procédé de production d'éthers, consistant à faire réagir un diène conjugué avec un alcool par télomérisation en présence d'une composition catalytique comprenant un composé de palladium, un isocyanure représenté par la formule générale (I) : R?1¿R?2¿R?3¿CNC et une base représentée par la formule générale (II) : M(OR?4¿)¿n? [dans ces formules, chaque symbole désigne un élément décrit dans la partie descriptive de la présente demande]. Ce procédé permet de produire industriellement des éthers par télomérisation d'un diène conjugué avec un alcool.
