Tervalent phosphorus acid derivatives

This chapter covers the most relevant literature published during the year 2019, related to tervalent phosphorus acid derivatives. Some of the most relevant concepts are reported, regarding synthetic methodologies to halogenophosphorus compounds, phosphorus esters (phosphites, phosphonites and phosphinites), phosphorus amides (aminophosphines phosphoramidites and diamidophosphites), and mixed phosphorus compounds bearing two different tervalent phosphorus moieties. A critical selection of their applications is discussed, with an emphasis on the catalytic applications of phosphorus (iii) ligands and metal complexes.
