| Abstract: | Several methods for the synthesis of the Pd38(CO)28L12 cluster (L = PEt3) by treatment of Pd10(CO)12L6 with CF3COOH-Me3NO, CF3COOH-H2O2, Pd(OAc)2-Me3NO, and Pd2(dba)3 mixtures (dba is dibenzylideneacetone) were proposed. The tri-n-butylphosphine analog, Pd38(CO)28(PBu3)12, was synthesized by the reaction of Pd10(CO)14(PBu3)4 with Me3NO. The reaction of Pd4(CO)5L4 with Pd2(dba)3 yields clusters with an icosahedral packing of the metal atoms, Pd34(CO)24L12 and Pd16(CO)13L9.Translated fromIzvestiya Akademii Nauk.
