“…However, the stabilization of the thus formed NPs has to be facilitated by coordinating protective ligands such as dendrimers, polymers and surfactants, providing electrostatic and/ or steric protection to avoid agglomeration. [54,55] Contrary to these classical methodologies, a single source process was recently introduced by our group using ethylene glycol metal carboxylates of type [L x M(O 2 CCH 2 (OCH 2 CH 2 ) n OMe) m ] y (L x M = (PR 3 ) 2 Cu, (PR 3 )Ag, (PPh 3 )Au, (PR 3 ) 2 Pd, (PR 3 ) 2 Pt, (PR 3 ) 2 (CO) 2 Ru, (PR 3 )Rh; n = 0, 1, 2, 3, 4, 5, 7.33; m = 1, 2; y = 1, 2) and [M(O 2 CCH 2 (OCH 2 CH 2 ) n OMe) m ] (M = Ag, Co, Cu; m, n = 1, 2) (Scheme 1). [56][57][58][59][60][61][62][63][64][65][66][67][68][69] The advantage of this approach is an easy reaction control over the straightforward formation of unique and tailored NPs with no need for both, the addition of reducing agents and stabilizing additives.…”
