| 其它 | Herein, we address the longstanding challenge of selective N-methylation and N-formylation coupling between CO2 and amines by developing tunable 2-aminopyridine–HBcat (catecholborane)/ HBpin (pincolborane) catalytic systems. This metal-free, solvent-free approach achieves remarkable chemo-switchable selectivity, enabling the divergent synthesis of various N-methylamines and N-formamides. Mechanistic investigations reveal that the observed high selectivity might be governed by both the structure of borane and its Lewis acidity. |
