Definitions
- the present invention relates to a method for producing ethers by a telomerization reaction of a conjugated diene compound.
- the ethers produced by the present invention are useful as raw materials for various polymers and intermediates such as fragrances.
- the telomerization reaction of a conjugated gen compound is a reaction in which the conjugated gen compound is oligomerized by incorporating a nucleophilic reactant such as an alcohol.
- a reaction in which two molecules of 1,3 butadiene reacts with one molecule of a compound containing active hydrogen such as acetic acid to produce 1-acetoxy 2,7 octadiene is exemplified.
- a palladium compound particularly a palladium compound coordinated with a phosphine compound, exhibits excellent activity as a catalyst for S-telomerization reaction (see Non-Patent Documents 1 and 2).
- a telomerization reaction using a catalyst comprising a tertiary phosphine compound or an isocyanide compound and a nickel compound has been reported (see Patent Document 1). Further, a telomerization reaction using a palladium carbene complex in the presence of a basic substance has been reported (see Patent Document 2). Furthermore, a telomerization reaction using a catalyst comprising a primary isocyanide compound and tetrakis (triphenylphosphine) palladium (see Patent Document 3) and a telomerization reaction using a catalyst comprising a tertiary isocyanide compound and a palladium compound (see Patent Reference 4) has been reported.

- Patent Document 1 requires high selectivity for by-products (about 10 to 30%) and low catalytic activity, and thus requires a large amount of catalyst. It is not an efficient method for producing ethers.
- Patent Document 3 uses a palladium compound to which a phosphine conjugate has already been coordinated. In this case, the coordination of the isocyanide compound to the palladium atom is suppressed, and the reaction is remarkably slowed down. The selectivity of the target product is lowered, and the yield is as low as about 17%. Not a way.
