A method for producing ethers comprises the following steps:
initiating telomerization process of a conjugated diene compound with an hydroxyl compound represented by the following formula (I):
R1OH (I)
in the presence of a palladium compound, a tertiary isocyanide represented by the following formula (II):
R2NC (II)
, and a base; and
adding halfway through the telomerization process a tertiary phosphine represented by the following formula (III):
PR3R4R5 (III)
(the respective symbols are defined in the description).
一种生产醚的方法包括以下步骤:
启动共轭二烯化合物与下式 (I) 所代表的羟基化合物的端聚过程:
R1OH (I)
在钯化合物存在下,加入下式 (II) 所代表的叔异氰酸酯:
R2NC (II)
和一种碱;以及
在端粒化过程的中途加入下式(III)代表的叔膦:
PR3R4R5 (III)
(各符号在说明中定义)。
