| 摘要 |
Mono-alkadienyl alkyl ethers and di-alkadienyl alkyl ethers are prepared by telomerization of a conjugated diene, by causing said conjugated diene to react with an aliphatic alcohol or an aliphatic diol respectively, by operating in an aqueous/organic biphasic liquid system, in the presence of a catalytic system formed by: -- (a) a palladium salt or complex; -- (b) an alkyl-, alkylcycloalkyl-, or alkylaryl-phosphine ligand, bearing an acidic or neutral hydrophylic moiety, having the formula: <CHEM> wherein R1, R2, R3, x and y are as defined in the disclosure; and -- (c) an either inorganic or organic base. |
