    • B-B) between B and B is in the order of tens of kHz. At -50 °C, the (coalesced, fast-exchange) signals of isomers B and B show slow-exchange crosspeaks with isomer A/D, with kinetics in the order of a few Hz. So the exchange of B/B with other isomers is several orders of magnitude less than the B-B exchange.

    • B resonances are found. However, at increasing temperatures, the water resonance shifts up field and the coalescence phenomena of 2 are well presented when monitoring the Me(i) signals.

    • The discussion regarding the direction of rotation is only valid for the Lambda enantiomeric atropisomers as depicted in Scheme 3. For the Delta atropisomers, which are indistinguishable from their mirror images in our NMR data, the direction of rotation is the opposite of what is discussed here.
