Carbonylation reactions with carbon monoxide (CO) provide efficient and attractive routes for the synthesis of bulk and fine chemicals. However, the practice of using a large excess of an inflammable, lethal and greenhouse CO gas is always a concern in this chemistry. The development of CO surrogates has gained substantial interest and become a green alternative to gaseous CO. Many of the recent studies have focused on the development of other benign and safe reagents to work as a CO source in carbonylation reactions, and the assortment of feasible CO surrogates for specific reaction can be accomplished by the literature data. This review describes the recent developments in palladium-catalyzed carbonyl insertions without the direct use of gaseous CO.

与一氧化碳（CO）的羰基化反应为合成大宗和精细化学品提供了有效且有吸引力的途径。但是，使用大量过量的易燃，致死和温室气体的做法一直是该化学过程中的关注点。一氧化碳替代物的开发引起了人们的极大兴趣，并已成为气态一氧化碳的绿色替代品。最近的许多研究都集中在开发其他可作为羰基化反应中一氧化碳来源的良性和安全试剂以及各种可行的一氧化碳上。特定反应的替代物可以通过文献数据来完成。这篇综述描述了在不直接使用气态CO的情况下钯催化羰基插入的最新进展。
