资源简介:
The barrier for the interconversion of the conformational atropisomers of an aryl fluorenylidene derivative was determined by variable-temperature NMR technique. In the case of a more hindered compound the two atropisomers were isolated and the structure determined by X-ray diffraction. The absolute configuration was assigned by theoretical interpretation of the Electronic Circular Dichroism spectrum (ECD).
