" /> α-cleavage - CISMeF





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.;
