Preferred Label : ipso-attack;
IUPAC definition : The attachment of an entering group to a position in an aromatic compound already
carrying a substituent group (other than hydrogen). The entering group may displace
that substituent group but may also itself be expelled or migrate to a different position
in a subsequent step. The term ' i ipso /i -substitution' is not used, since it is
synonymous with substitution. For example: where E is an electrophile and Z is
a substituent (other than hydrogen).;
