Organophosphines are organophosphorus compounds with the formula PR n H 3−n, where R is an organic substituent. These compounds can be classified according to the value of n: primary phosphines (n = 1), secondary phosphines (n = 2), tertiary phosphines (n = 3). All adopt pyramidal structures. [1]
General formula of organophosphine oxides. Phosphine oxides are phosphorus compounds with the formula OPX 3. When X = alkyl or aryl, these are organophosphine oxides. Triphenylphosphine oxide is an example. An inorganic phosphine oxide is phosphoryl chloride (POCl 3). [1] The parent phosphine oxide (H 3 PO) remains rare and obscure.
With the formula (HO) 2 P(O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides. Bisphosphonates are a class of drugs to treat osteoporosis. The nerve gas agent sarin, containing both C–P and F–P bonds, is a phosphonate. [citation needed] Phosphinates feature two P–C bonds, with the general formula R 2 ...

A metal-phosphine complex is a coordination complex containing one or more phosphine ligands. Almost always, the phosphine is an organophosphine of the type R 3 P (R = alkyl, aryl).
Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C 6 H 5) 3, also written as Ph 3 PO or PPh 3 O (Ph = C 6 H 5). It is one of the more common phosphine oxides. This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine.
