Summary:To provide a methoxycarbonylation method using formic acid as a CO source.SOLUTION: There is provided a methoxycarbonylation method of olefin having a) a step of adding olefin; b) a step of adding a compound containing Pd, in which Pd can form a complex; c) a step of adding a compound of the formula (I); d) a step of adding MeOH and HCOOH, in which a ratio of MeOH/HCOOH by used volume basis of 1.55:0.45 to 1.1:0.9; and e) a step of heating the reaction mixture and converting the olefin to methylester. In the formula, R, R, Rand Rare each independently H, C1 to 12 alkyl, C1 to 12 alkoxy, C4 to 14 aryl, C4 to 14 aryloxy, cycloalkyl, C1 to 12 heteroalkyl, C1 to 12 heteroaryl or the like, but at least one of R, R, Rand Ris not phenyl.SELECTED DRAWING: None 【課題】ギ酸をCO源として用いるメトキシカルボニル化方法の提供。【解決手段】a)オレフィンを添加する工程;b)Pdを含有する化合物を添加する工程であり、該Pdが錯体を形成することができる工程;c)式(I)の化合物を添加する工程;d)MeOHおよびHCOOHを添加する工程であり、使用体積基準で前記MeOH/前記HCOOHの比が1.55:0.45〜1.1:0.9の範囲である工程;及びe)当該反応混合物を加熱して前記オレフィンをメチルエステルに転化する工程を有するオレフィンのメトキシカルボニル化方法。(R1、R2、R3、R4は各々独立にH、C1〜12アルキル、C1〜12アルコキシ、C4〜14アリール、C4〜14アリールオキシ、シクロアルキル、C1〜12ヘテロアルキル、C1〜12ヘテロアリール等;但し、R1、R2、R3、R4の少なくとも1つはフェニルではない。)【選択図】なし
