The reaction of hydrazine hydrate with KSeCN in acidic aqueous ethanol in the presence of cyclohexanone affords cyclohexanone selenosemicarbazone in good yields. Cyclohexanone selenosemicarbazone was converted into various functionalised selenosemicarbazones by treatment with aldehydes. Salicylaldehyde selenosemicarbazone and its 1,2-naphthyl-derivative were prepared and reacted with some Pd(II) and Pt(II) phosphine complexes to give compounds of the type [M(L(Se))(P)] where M = Pt and Pd, L(Se) is the doubly deprotonated selenosemicarbazone and P a monodentate phosphine. In these complexes the ligands act as tridentate, dianionic [Se-NeO](2-) ligands, which was confirmed by single-crystal X-ray diffraction of the Pd derivative. (C) 2010 Elsevier B.V.
