Roaming-mediated ultrafast isomerization of geminal tri-bromides in the gas and liquid phases.

Nature Chemistry 7 , 562-8, (2015)

'Roaming' is a new and unusual class of reaction mechanism that has recently been discovered in unimolecular dissociation reactions of isolated molecules in the gas phase. It is characterized by frustrated bond cleavage, after which the two incipient fragment...
