PROBLEM TO BE SOLVED: To provide an industrially and economically advantageous manufacturing method of carboxylic acid prenyl and prenol in a high yield under a mild condition.SOLUTION: In a manufacturing method, allyl alcohol represented by the formula (1) is reacted with carboxylic acid anhydride represented by the formula (2) in a presence of an oxovanadium complex prepared by reacting trialkoxy oxovanadium and a pyridinecarboxylic acid derivative, thereby obtaining allyl ester represented by the formula (3). Further, carboxylic acid prenyl is subjected to solvolysis, thereby obtaining prenol represented by the formula (4).SELECTED DRAWING: None 【課題】カルボン酸プレニル類及びプレノール類を温和な条件下で、高収率で工業的及び経済的に有利な製造方法の提供。【解決手段】式（１）で表わされるアリルアルコール類をトリアルコキシオキソバナジウムとピリジンカルボン酸誘導体とを反応させて調製されるオキソバナジウム錯体の存在下、式（２）で表わされるカルボン酸無水物と反応させて式（３）で表わされるアリルエステル類の製造し、さらに該カルボン酸プレニル類を加溶媒分解して、式（４）で表わされるプレノール類を得る製造方法。【選択図】なし
