organoheteryl groups
Univalent groups containing carbon, which are thus organic, but which have their free @V06588@ at an atom other than carbon. This collective term is seldom used; specific subclasses are more frequently encountered (organothio or organylthio, organogermanium or organylgermanium groups). The synonymous term organoelement groups is occasionally encountered. E.g. phenoxy, acetamido, pyridinio (C5H5N+), thiocyanato (N≡C–S), trimethylsilyl; but not hydroxyphenyl, aminoacetyl.
