Phosphonic acid, as name for

Phosphine oxide, tri-re-butyl-, 6 90 Phosphonic acid, as name for HsP03, 4 57... 

Again, the recommended names (phosphonic acid and phosphonates) have found more general acceptance for organic derivatives such as RP03 , and purely inorganic salts are still usually called phosphites. The free acid is readily made by direct hydrolysis of PC l3 in cold CCI4 solution ... 

Esters of phosphinic acid, H2P(0)(0H), are named by the same methods as used for phosphonates. For examples with two P-C bonds see 2-Carb-31.3. 

Various types of phosphorus reagents have been employed for asymmetric transformations of carbonyl compounds into alkenes [2, 4, 7-11]. Depending upon the structure of these reagents, different reaction names are given [3]. Phosphonium ylides and phosphine oxide are particularly popular, and are referred to as Wittig and Horner reagents, respectively. On the other hand, phosphonates and other phosphonic acid derivatives are termed Horner-Wadsworth-Emmons (HWE) reagents. In recent years, arsonium derivatives have often been used for similar reactions, and they are also covered herein.
