“…Organophosphorus compounds including P ‐heterocycles may find applications in synthetic organic chemistry as reactants, solvents (ionic liquids), catalysts, P ‐ligands in complexes, and due to their biological activity also as drugs and plant protecting agents . The utilization of MW irradiation in organophosphorus chemistry is a relatively new field …”

A personal account on the pioneering results on microwave (MW)-assisted organophosphorus syntheses obtained in the last decade is presented. The broad spectrum of the reactions studied exemplifies the advantages of the MW technique as a green tool regarding efficiency and the simplification of catalyst systems. Theoretical calculations for a few typical models helped us to explore the scope and limitations of the application of MW irradiation.

“…5 The Keglevich group elaborated the synthesis of P-heterocycles and other phosphinic, phosphonic, and phosphine oxide derivatives utilizing the MW technique. [6][7][8][9][10][11][12] The reactions investigated are shown in Figure 1. The role of MWs in organic syntheses induced vehement disputes that led to different theories.…”

The microwave (MW) technique has become an important tool also in the organophosphorus field of organic chemistry. On the one hand, otherwise reluctant reactions, such as the esterification of P-acids, may be enhanced by the effect of MW, while on the other hand, catalysts may be omitted, or catalyst systems may be simplified on MW irradiation. This later group includes the Kabachnik–Fields reactions, alkylation of active methylene-containing compounds, O-alkylations, deoxygenations, as well as the Hirao reaction. It is also the purpose of this review to elucidate the scope and limitations of the MW tool, to interpret the MW effects, and to model the distribution of local overheatings and their beneficial effect.1 Introduction2 The Esterification of Phosphinic Acids2.1 Synthetic Results2.2 Scope and Limitation of the Application of MWs2.3 Modelling the Distribution of the Local Overheatings and Predicting Their Effect3 The Simplification of Catalytic Systems3.1 Replacement of the Catalyst by MW Irradiation3.1.1 The Kabachnik–Fields Reaction3.1.2 Solid–Liquid Phase Alkylation of Active Methylene-Containing Compounds3.1.3 Solid–Liquid Phase Alkylation of Phosphinic Acids3.1.4 The Deoxygenation of Phosphine Oxides3.2 The Hirao Reaction without Added P-Ligands4 Conclusions

“…As such, this novel approach was, of course, applied also in organophosphorus chemistry from the beginning (*1980), however, the real break-through happened much later. Guenin was the first, who collected the examples of MW-assisted organophosphorus reactions into a review article [1] that was followed by a few others compiled mainly by the author of this chapter [2][3][4][5][6][7].…”

The third chapter summarizes a special field, the application of the microwave (MW) technique in the synthesis of organophosphorus compounds. On the one hand, reactions are shown that are otherwise rather reluctant on traditional thermal heating. On the other hand, reactions are discussed, which, became more efficient (shorter reaction times and higher yields) on MW irradiation. Finally, the simplification of catalytic systems under MW conditions are surveyed.
