“…The relative position of the two P(III)-functions was confirmed by 31 P NMR spectral data and quantum chemical calculations [65,[84][85][86][87][88]. It is noteworthy, that the platinum complex of the 3-diphenylphosphino-1-phenyl-1,2,3,6-tetrahidrophosphinine (36*) was also prepared in an optically active form [65].…”

The use of the microwave (MW) Keywords organophosphorus chemistry, green chemistry, microwave, resolution, platinum complexes, dronic acids/dronates IntroductionIn this minireview, our recent results in environmentallyfriendly ("green") chemistry have been summarized. In the first sub-chapter the usefulness of the microwave technique is shown in organophosphorus chemistry. The second sub-chapter summarizes our results on the resolution of cyclic phosphine oxides, as precursors for P-ligands and on the synthesis of platinum complexes as potential catalysts. Catalysts are of utmost importance from the point of view of green chemistry. The last sub-chapter comprises our experiences on the optimization of the synthesis of dronic acid derivatives that are important drugs against bone diseases.

“…Scheme 3.25 MW-assisted Arbuzov reaction of aryl halides and triethyl phosphite species had to be converted to the corresponding anion by deprotonation with trimethylaluminum [57,58]. In these reactions, MW irradiation was unable to enhance the addition of the >P(O)H species to the not too reactive CH=CH-P(O)< unsaturation of the reactants.…”

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.

“…In this series, only DuPhos has been applied in platinum complexes [18][19][20]. 3-Diphenylphosphino-1-phenyl-1,2,3,6-tetrahydrophosphinine and its 1,2,3,4,5,6-hexahydrophosphinine derivative were also described as novel bidentate P-ligands in Pt(II) complexes [21][22][23][24][25][26] showing unusual regioselectivity as catalysts in the hydroformylation of styrene [27].…”
