Organophosphate
Organophosphates (also known as phosphate esters) are a class of organophosphorus compounds with the general structure O=P(OR). They can be considered as esters of phosphoric acid. Like most functional groups organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, and nerve agents.
Organophosphorus compound
Intermediate between phosphites and phosphines are phosphonites (P(OR)R') and phosphinite (P(OR)R'). Such species arise via alcoholysis reactions of the corresponding phosphinous and phosphonous chlorides ((PClR') and PClR', respectively).
