Sažetak
It is reported that some unstable species, such as cyclopropylcarbinyl-, cyclooctyl-, 2-butyl- and 7-norbornyl- carbocations, can be prepared in the SbF5 matrix and investigated by IR spectroscopy combined with high level ab initio calculations. Direct measurements of the changes in bond strenghts, i.e. changes of vibrational frequencies (Av/cm-l) induced by forming the cationic species, could yield fundamental information on the neighboring group effects. Results of systematic investigations along these lines include studies of the complexes of nitriles and ketones with SbF5, ally1 and propargyl cations and chlorocarbocations.
