A Stable Primary Phosphane Oxide and Its Heavier Congeners

Popis výsledku v původním jazyce

(Ferrocenylmethyl)phosphane (1) oxidation with hydrogen peroxide, elemental sulfur and grey selenium produced (ferrocenylmethyl)phosphane oxide 1O, sulfide 1S and selenide 1Se, respectively, as the first isolable primary phosphane chalcogenides lacking steric protection. At elevated temperatures, compound 1O disproportionated into 1 and (ferrocenylmethyl)phosphinic acid. In reactions with [(η(6)-mes)RuCl2](2), 1O underwent tautomerization into a phosphane complex [(η(6)-mes)RuCl2{FcCH(2)PH(OH)-κP}], whereas 1S and 1Se lost their P-bound chalcogen atoms, giving rise to the phosphane complex [(η(6)-mes)RuCl2(FcCH(2)PH(2)-κP)] (Fc = ferrocenyl, mes= mesitylene). No tautomerization was observed in the reaction of 1O with B(C6F5)(3), which instead produced a Lewis pair FcCH(2)P(O)H-2-B(C6F5)(3). Phosphane oxide 1O added to C=O bonds of aldehydes and ketones and even to cumulenes PhNCE (E=O and S). However, both PH hydrogens were only employed in the reactions with aldehydes and cyanates.
