Rare Earth Arene-Bridged Complexes Obtained by Reduction of Organometallic Precursors

“…Unlike main group elements and late transition metals (Caporali et al, 2010;Scheer et al, 2010), the number of Pn-containing early transition metal complexes formed from direct P4 activation is much smaller (Chirik et al, 2002;Cossairt et al, 2010b;Hey et al, 1987;Scherer et al, 1988;Seidel et al, 2009). Among early transition metals, rare earths are more Lewis acidic, leading to a more pronounced mismatch in binding between their ions and phosphorous anions (Cui et al, 2008;Lv et al, 2011;Masuda et al, 2008).…”

“…White phosphorous (P4) activation has been long targeted by synthetic chemists (Caporali et al, 2010;Cossairt et al, 2010b;Scheer et al, 2010). Unlike main group elements and late transition metals (Caporali et al, 2010;Scheer et al, 2010), the number of Pn-containing early transition metal complexes formed from direct P4 activation is much smaller (Chirik et al, 2002;Cossairt et al, 2010b;Hey et al, 1987;Scherer et al, 1988;Seidel et al, 2009).…”

P4 Activation by Lanthanum and Lutetium Naphthalene Complexes Supported by a Ferrocene Diamide Ligand

“…Though easily activated, the activation of P4 is not easily controlled. [5][6][7] P4 activation by main group and transition metals has been of long-standing interest. [5][6][7] Alkali metals and late transition metals compose the majority of examples of direct P4 activation.…”

[5,6] On the contrary, early transition metal mediated P4 activation is much less investigated and rare-earth examples are rare. [7][8][9][10][11][12][13] Roesky et al reported the formation of (Cp * 2Sm)4P8 from slow vapour transfer of P4 into a toluene solution of Cp * 2Sm.…”
