Abstract:
Triarylmethanols - the direct precursors of persistent trityl radicals - are racemic mixtures of chiral three-bladed molecular propellers. Depending on the bulkiness of the aryl groups, they exhibit various tendencies to interconvert, and the half-life of room-temperature racemization varies between 8.4 h and 1.32 years. NOESY/EXSY experiments performed on two representative models strongly support the two-ring flip mechanism for the configurational interchange.
