The capture and utilization of CO by 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD) were performed in the absence of transition‐metal complexes. The reaction of TBD with CO afforded TBD‐CO adducts, which were converted to formylated TBD (TBD‐CHO). TBD‐CO adducts may include an interaction of CO with positively charged species based on NMR and IR analysis. In the presence of amines, CO was transferred from TBD‐CO to amines, producing formylated amines with good yields. The reaction mechanism involving TBD‐CO adducts is presented based on theoretical calculations.
