资源简介：
Two 24-member diamine-tetraamido macrocycles (R = H and CH3), readily synthesized in one or two steps, were found to react with CO2 rapidly and efficiently (100% conversion within 1 min at rt). The resulting carbamate formation was demonstrated by 1H, 13C NMR, ESI-MS, and X-ray crystallography. The crystal structure clearly showed the carbamate group (N-CO2–) formed was tightly bound within the macrocyclic cavity, held by five internal hydrogen bonds, and stabilized by intramolecular carbamate-ammonium salt-bridge formation.
