ACD/Name
Note that, in contrast to the Rules given in Section A, this rule does not require that a free valence terminates the chain (cf. Rules A-2.25, A-3.5). Note also that the suffixes "-ylidene", "-ylidyne" and "-ylene" codified in Section A and B are not included here. The Commissions are continuing to study these areas.
