The objective of this review is to summarize recent progress and advances in the synthesis of hydroxymethyl-alcohols through the direct hydroxymethylation of unsaturated hydrocarbons using CO₂ as the carbonyl source with insightful mechanistic discussions. Depending on the unsaturated substrates employed the paper is divided into three sections. The first section focuses exclusively on hydroxymethylation of alkenes. The second covers hydroxymethylation of allenes. The third section gives a brief overview of the hydroxymethylation of alkynes.

用 CO ₂对不饱和烃进行羟甲基化：概述

本综述的目的是通过深入的机理讨论，总结通过使用 CO ₂作为羰基源的不饱和烃的直接羟甲基化合成羟甲基醇的最新进展和进展。根据所使用的不饱和基材，纸张分为三个部分。第一部分专门关注烯烃的羟甲基化。第二个涉及丙二烯的羟甲基化。第三部分简要概述了炔烃的羟甲基化。
