Synthesis, reactivity and coordination behaviour of a ferrocene phosphinostibine and intramolecular interactions in its P(V) and Sb(V) derivatives
Original language description
Compared to their P,N-analogues, compounds combining P and Sb substituents remain less common. This contribution describes the synthesis of a new ferrocene phosphinostibine, Cy2PfcSbPh2 (3; fc = ferrocene-1,1'-diyl, Cy = cyclohexyl), and its derivatives modified at the phosphine and stibine moieties, viz., Cy2P(E)fcSbPh2 (E = BH3, O, S, AuCl), Cy2P(E)fcSbCl2Ph2 (E = BH3, S, AuCl) and stiboranes Cy2P(E)fcSb(O2C6Cl4)Ph2 (E = void, BH3, O, S and AuCl). The increased Lewis acidity of the Sb atom in the catecholatostiboranes Cy2PfcSb(O2C6Cl4)Ph2 and Cy2P(O)fcSb(O2C6Cl4)Ph2 resulted in intramolecular P -> Sb and O -> Sb dative interactions, which were not detected for the respective parent stibines or even in Cy2P(S)fcSb(O2C6Cl4)Ph2. While the P -> Sb interaction in Cy2PfcSb(O2C6Cl4)Ph2 was stronger than that in the "all-phenyl" analogue Ph2PfcSb(O2C6Cl4)Ph2 due to the electron-donating effect of the cyclohexyl groups, the bonding situations in Cy2P(O)fcSb(O2C6Cl4)Ph2 and Ph2P(O)fcSb(O2C6Cl4)Ph2, where the substituent effect was only indirect, remained very similar according to DFT calculations. A coordination study with 3 resulted in isolation of phosphine ([AuCl(3-κP)]), P,Sb-bridging ([(μ(P,Sb)-3)(AuCl)2]), and P,Sb-chelate ([(arene)MCl(3-κ(2)P,Sb)]X, where (arene)M/X = (η(6)-p-cymene)Ru(II)/PF6, (η(5)-C5Me5)Rh(III)/Cl, and (η(5)-C5Me5)Rh(III)/PF6, and [MCl2(3-κ(2)P,Sb)], where M = Pd and Pt) complexes. For some of these compounds, structure determination revealed structural distortions suggesting weak intramolecular Cl-Sb interactions, which were confirmed by theoretical methods.
