Volume 18: Four Carbon¾Heteroatom Bonds
|
 |
Introduction by Dr. Julian Knight (Volume Editor): |
| This volume concerns the synthesis of functional groups in which carbon has four bonds
to heteroatoms. This represents an enormously diverse range of chemistry, and a correspondingly
wide variety of functionality, from highly unsaturated systems such as heterocumulenes
(e.g., carbon dioxide) to compounds with no p-bonds, such as carbon tetrafluoride.
Despite this diversity, much of the chemistry is dominated by that of the carbonyl
group and its direct heteroatom analogues, such as the imino and thiocarbonyl groups.
A central role is played by phosgene (COCl2) which, despite its toxicity, is a useful precursor
to many of the other functional groups in Volume 18. While most of the compound
classes have been known for a very long time, some have proven more elusive and have
only recently been prepared and identified, through advances in synthetic methodology
and spectroscopic techniques. Such compounds include phosphaalkene and phosphaalkyne
derivatives, and several selenium- and tellurium-based functional groups..
