Various primary amines and secondary amines are successfully transformed into the corresponding formamides under mild conditions, and the formylation of primary diamines is also achieved. The chromium catalyst can be reused several times with little loss of the activity. Mechanistic insight is provided ...

DFT计算表明结果，催化剂Cu3S3位点的Lewis酸碱性解释了苯胺N-甲酰化的关键步骤。适当碱度的Na2CO3助催化剂对提高收率也至关重要，不仅提高了对苯胺前体和CO的吸附，而且防止了对催化剂有毒的离子中间体的过度稳定吸附。Atomically Precise AgCu Clusters Affixed to SiO2 Aerogel for N-Formylation of Amines. ACS ...
N-formylation of a wide range of amines proceeded using copper-diphosphine complexes as homogeneous catalysts with polymethylhydrosiloxane (PMHS) under 1 atm of CO2. In the reaction of piperidine, for example, the turnover number (TON) reached 11700 in 23 h with 90% yield of the formylated...
A simple, efficient, scaleable process has been developed for the N-formylation amines in water. Treatment of amines with triethyl orthoformate in water at reflux under neutral conditions without any additives gives the corresponding N-formyl derivatives in good yields.关键词: N-formylation amines or...
