One chemist developed magic acid to study these chemicals, resolving a dispute about the nonclassical structure of a norbonyl compound of this type.  These molecules may undergo one-two rearrangement reactions, such as the Wagner-Meerwein reaction. Those rearrangements, including methyl and hydride shifts, usually increase the degree of substitution. Studied by George Olah, these may interact with neighboring eclipsing sigma bonds in a process called hyperconjugation.  These species appear as intermediates in certain unimolecular reaction pathways, such as E-one and SN-one where their formation is governed by Markovnikov's rule.  FTP, name this class of molecules, which are common targets of nucleophiles, and which contain a positively charged carbon atom.
