... 3 ©HSO,, diethyl ether oxonium salt The hydrocarbon, pentane, fails to
produce the oxonium salt. The oxonium salt formed by diethyl ether is soluble in
H2SOi». Thus, diethyl ether leaves the homogeneous solution and dissolves in
the acid.

Organic Chemistry: An Acid—Base Approach
Oxonium salt 45 is related to the hydronium ion (H3O+) in that two hydrogen
atoms have been replaced with alkyl groups, and it is an obvious analog of the
oxonium salt derived from ethanol (see 13). Oxonium salts such as 45 are very
strong ...

The monohydrochloride is yellow while the salt containing an excess of
hydrochloric acid is colorless. The excess of hydrochloric acid may be absorbed
by the ketone group, forming an oxonium salt or a carbonium salt. Cl Cl / / H — N

Rimmelin and Sommer tested this hypothesis by synthesising an oxonium salt
and reacting it with a strong organic base, called tetramethylpiperidyl lithium. The
base pulls a proton off one of the oxonium salt's methyl groups, forming the ...
