The carboxylation of propargylic alcohols containing a silyl group at the terminal position was conducted in a CO₂ atmosphere at atmospheric pressure in the presence of a nickel catalyst and diethylzinc. Here, CO₂ was used as not only the C1 source but also the promoter of the C–OH cleavage processes for the oxidative addition of propargylic alcohols.

镍催化二氧化碳对丙醇的直接羧化反应

在大气压下，在CO ₂气氛中，在镍催化剂和二乙基锌的存在下，在末端位置上含有甲硅烷基的炔丙醇的羧化反应。在这里，CO ₂不仅用作C1的来源，还用作C-OH裂解过程的促进剂，用于氧化添加炔丙醇。
