Quinquevalent phosphorus acids
This chapter shows, as in previous years, the most important achievements, published in leading journals in 2014, in the area organophosphorus compounds containing three P–O bonds (phosphates), two P–O and one P–C bonds (phosphonates) as well as one P–O and two P–C bonds (phosphinates) in addition to the phosphoryl group PO. Heteroanalogs of phosphates, phosphinates and phosphonates containing combinations of P–X and PY bonds (X, Y=O, N, S, Se) have also been described. Each of the main sections has been traditionally divided in the same way, covering synthesis, reactions ad biological aspects. New subsubsections devoted to miscellaneous applications of phosphoric, phosphonic and phosphinic acids and their derivatives, other than biological ones, have been added for the first time in this volume. The total number of contributions remained during the review period almost on the same level of 263 in 2014
