The azamacrocyclic complex was used as a platform for the construction of [3]rotaxanes containing two DB24C8 macrocycles per molecule. The complex unit incorporates two electron deficient π-bond systems and two N-H hydrogen bond donating groups which faci

Reported herein is the iridium-catalyzed direct amidation of unactivated sp3 C-H bonds. With sulfonyl and acyl azides as the amino source, the amidation occurs efficiently under mild conditions over a wide range of unactivated methyl groups with high functional group tolerance. This procedure can be successfully applied for the direct introduction of an amino group into complex compounds and thus can serve as a powerful synthetic tool for late-stage C-H functionalization.
Use of an aromatic polyimide as a non-cross-linked molecular imprinting material
Lim, Chae Hyun,Ki, Chang Do,Kim, Tae Hoon,Chang, Ji Young
, p. 6 - 8 (2007/10/03)
The use of a rigid non-cross-linked polymer in molecular imprinting was explored. Aromatic polyimides have excellent thermal stability and mechanical strength, which have contributed to their successful application in several areas, such as films, molding
