A pillar[5]arene with an amino-terminated arm stabilizes the formation of aliphatic hemiaminals and imines†
Abstract
We report a new mono-armed pillar[5]arene with the amino-substituent self-included in the pillarene cavity, which can stabilize the hemiaminals and imines formed from the reaction of aliphatic amines and aldehydes as monitored by mass spectroscopy.
