Preferred Label : α-cleavage;
Detailed label : α-cleavage (alpha-cleavage);
IUPAC definition : mass spectrometry the fission of a bond originating at an atom which is adjacent to
one assumed to bear the charge; the definition of ß-, ¿-, cleavage then follows automatically.
the process: would thus be described as a-fission of a ketone with expulsion of a
radical r11. the carbon atoms of the radical r11are called the a-, ß-, ¿-carbons,
starting with the atom nearest the functional group.;
Scope note : this reaction should be distinguished from an alpha-(a-)elimination.;
Origin ID : A00004;
