To understand carbocations is to understand chemistry
-
(Meerwein) in the 1920s and 1930s started detailed studies of how chemical reactions between organic molecules took place it, however, became apparent that positively charged hydrocarbons - what chemists call "carbocations" - actually could occur as very short lived (lifetimes of microseconds to nanoseconds) intermediates in the reactions.
-
Such carbocations were, however, thought to be so reactive and unstable that it would be impossible to prepare them in quantity.

Olah's investigations, starting in the 1960s, contradicted this supposition, since he showed that stable carbocations can be prepared by the use of a new type of extremely acidic compounds

-
As a result, we found that the emergence of electrical conductivity on the doped polyacetylene was due to the creation of carbocations or positively charged solitons associated with withdrawing of p electrons from polyacetylene by the dopant when iodine was used as an acceptor dopant.
-
The fundamental chemistry of such hydrocarbon conversions involves carbocations and their reactions.

-
These processes are frequently catalyzed by acids and involve electron deficient intermediates called carbocations.

In such superacidic media the lifetime of carbocations are sufficiently long to be examined by a variety of chemical and physical methods including nuclear magnetic resonance spectrometry.

Olah's discovery resulted in a complete revolution for scientific studies of carbocations, and his contributions occupy a prominent place in all modern textbooks of organic chemistry.

However, nobody was able to see these carbocations, not even with the most powerful microscopes or by spectroscopic methods.
