PROBLEM TO BE SOLVED: To provide a process for alkoxycarbonylation of long-chain ethylenically unsaturated compounds, such as C8 olefins, which can achieve a high yield and high n/iso selectivity.SOLUTION: The invention relates to a process comprising the following steps: a) introducing an ethylenically unsaturated compound; b) adding a monophosphine ligand and a compound comprising Pd, or adding a complex comprising Pd and a monophosphine ligand; c) adding an aliphatic alcohol; d) supplying CO; and e) heating the reaction mixture to react the ethylenically unsaturated compound to form an ester; where the monophosphine ligand is, e.g., of formula (2).SELECTED DRAWING: None 【課題】長鎖エチレン性不飽和化合物、例えばＣ８オレフィンのアルコキシカルボニル化方法であって、高収率および高ｎ／ｉｓｏ選択性を達成することができる。【解決手段】ａ）エチレン性不飽和化合物を導入する工程と、ｂ）モノホスフィンリガンドとＰｄを含む化合物とを添加する工程、またはＰｄ含有錯体とモノホスフィンリガンドとを添加する工程と、ｃ）脂肪族アルコールを添加する工程と、ｄ）ＣＯを供給する工程と、ｅ）前記反応混合物を加熱し、前記エチレン性不飽和化合物を反応させてエステルを形成する工程と、を含む方法で、前記モノホスフィンリガンドが例えば式（２）である。【選択図】なし
