The well-defined 1,1′-bicyclopentadiene derivatives have been prepared by an endo-endo mode intramolecular reductive cyclization of a 1,4-diyne using lithium naphthalenide followed by oxidative coupling via a higher order cyanocuprate. The crystal structure and UV spectra of the bicyclopentadienes have also been determined.
Developing norbornadiene–quadricyclane (NBD–QC) systems for molecular solar-thermal (MOST) energystorage is often a process of trial and error. By studying a series of norbornadienes (NBD-R2) doubly substituted at the C7-position with R = H, Me, and iPr, we untangle the interrelated factors affecting MOST performance through a combination of experiment and theory.
