The 3-chloro(methyl)cyclopentyl cation and its reaction with carbon monoxide. The ionization mechanism of trans-1,2-dichlorocyclohexane in super acid (FSO3H–SbF5)
Abstract
The title ion (5) was identified as the intermediate in the ionization of trans-1,2-dichlorocyclohexane in super acid solution; it is stable to about –50 °C and it is attacked by CO at –78 °C predominantly (93 : 7)cis to the chlorine substituent.
