Abstract :
[en] Two tripodal alcohols, viz., 1,1,1-tris(hydroxymethyl) ethane and alpha, alpha, alpha-tris(hydroxymethyl) toluene were converted by an efficient multi-step pathway involving azide formation into the corresponding tris(iminophosphorane) scaffolds bearing cyclopentyl (Cp) or phenyl groups on their phosphorus atoms, R-C(CH2-N] PR'(3))(3) (R Me or Ph, R'=Cp or Ph). The synthesis of some representative transition-metal complexes of Cu(I), Cu(II), Ni(II), and Pd(II) bearing these new tridentate ligands is also reported. (C) 2007 Elsevier Ltd. All rights reserved.
