Reactivity of bis(organoamino)phosphanes with magnesium(II) compounds
Original language description
The reactivity of three phosphanes (PhP(NHR)(2) [R = t-Bu (1), Ph (2)] and PhP(NEt2)(NHDip) (3) (where Dip = 2,6-i-Pr2C6H3)) with n-Bu2Mg and MeMgBr is presented. In the case of 1, the reaction with n-Bu2Mg gave [PhP(NHt-Bu)(Nt-Bu)] Mg(n-Bu) (4) or [PhP(NHt-Bu)(Nt-Bu)](2)Mg (5) depending on the stoichiometry. The treatment of 1 with MeMgBr led to the phosphinate [Ph(H)P(Nt-Bu)(2)](2)Mg (7) as a result of both the NH -> PH tautomeric transformation and elimination of MgBr2 from the non-isolable intermediate [PhP( NHt-Bu)(Nt-Bu)]MgBr(THF) (6). Phosphane 2 reacted with n-Bu2Mg in a 1 : 1 molar ratio resulting in the formation of {[PhP(NPh)(2)](2)Mg(THF)(2)}(2) (8), but the analogous reaction in a 2 : 1 molar ratio yielded phosphinate [Ph(H)P(NPh)(2)](2)Mg(THF) (9). The heteroleptic compound [Ph(H)P(NPh)(2)]MgBr(THF)(2) (10) was obtained by the reaction of 2 with MeMgBr. Finally, the reaction of 3 with n-Bu2Mg and MeMgBr produced compounds [PhP(NEt2)(NDip)](2)Mg (11) and {[PhP(NEt2)(NDip)(
