Publikováno v: Organic Letters, 21 (1)

A series of quinoxaline cavitands bearing pendant amide groups with various substituent sizes (Et, iPr, tBu) were synthesized, and their cavity size/structure were investigated by X-ray and NMR analyses. In the case of the Et or iPr amide cavitand, t

A Cu-I bis-phenanthroline rotaxane was prepared by using the [2+2] cycloaddition-retroelectrocyclization (CA-RE) reaction to graft a bulky dicyanoquinodimethane (DCNQ) stopper. The electronic properties were investigated with electrochemical and phot

Publikováno v: Chem. Eur. J.

A variety of asymmetrically donor-acceptor-substituted [3]cumulenes (buta-1,2,3-trienes) were synthesized by developed procedures. The activation barriers to rotation ΔG(≠) were measured by variable temperature NMR spectroscopy and found to be as
