Preferred Label : abeo-;
IUPAC definition : Bond migration, i.e. the formal transfer of one end of a skeletal bond to another
position, with a compensating transfer of a hydrogen atom, can be indicated by a prefix
of the form 'x ( y z ) i abeo- /i '. The prefix is compiled as follows: a numeral
denoting the stationary (unchanged) end of the migrating bond ( i x /i ) is followed
by parentheses enclosing the locant denoting the original position ( i y /i ) from
which the other end of this bond has migrated, an arrow, and the locant ( i z /i )
denoting the new position to which the bond has moved. The closing parenthesis is
followed by the italicized prefix i abeo /i - (Latin: I go away) to indicate bond
migration. The original numbering is retained for the new compound and is used for
the numbers i x /i , i y /i and i z /i . It is always necessary to specify the
resulting stereochemistry.;
