Organophosphorus and Organoarsenic Compounds

Organophosphorus chemistry is complicated by the stability of P(V) species in addition to trivalent species snch as phosphines, and the possibility of tautomerism between them. In addition, many phosphorns componnds have been named as inorganics or biochemicals, as well as by the methods of organic nomenclature, leading to a proliferation of names. 

An extensive Dictionary of Organophosphorus Compounds (compiled by R. E. Edmundson) was pnblished in 1988, and has been updated as part of the CRC database (see Section 1.2.1). It gives an extensive selection of alternative names. Substructure searching to locate compounds of analogons strnctnre can often resolve nomenclature difficulties for the commoner types. Organoarsenic nomenclature is analogous. 

Many phosphorns (and arsenic) compounds are named using functional replacement nomen-clatnre in which replacement affixes are inserted into the names of the appropriate phosphorus
