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.
Phanephos
Phanephos is an organophosphorus compound with the chemical formula (CH)(CHPPh) (Ph = CH). It is a white solid that is soluble in organic solvents. It is an example of a chiral C-symmetric diphosphine ligand used in asymmetric hydrogenation. Many substituents have been introduced in place of the phenyl groups, e.g., "i"-Pr, CH, etc and a variety of chiral diphosphine ligands have been reported in asymmetric catalysis since the 1960s.
