Full title: Addition of mercury(II) electrophiles to [Ru2(C10H8N2)(CO)4(P iPr3)2] and selective insertion versus addition in the reactions of mercury (II) electrophiles with trinuclear Ru2Hg clusters. X-ray structures of [Ru2Hg(O2CCF3)2(C10H 8N2)(CO)4(PiPr3) 2] and [Ru2Hg2Cl4(C10H8N 2)(CO)4(PiPr3) 2]·CH2Cl2 (C10H10N2 = 1,8-diaminonaphthalene). The ruthenium(I) complex [Ru2(C10H8N2)(CO)4(P iPr3)2] (1) (C10H10N2 = 1,8-diaminonaphthalene) reacts with 1 equiv of HgX2 (X = Cl, Br, I, O2CCH3, O2CPh, O2CCH2Cl, O2CCF3, SCN, ONC) to give the adducts [(1)HgX2], in which the Hg atoms are bonded to both Ru atoms of complex 1. Correlations between the 2J(31P-199Hg) coupling constants of their 31P NMR spectra and the corresponding halogen electronegativities or acid pKas have been observed. With the exception of [(1)Hg(O2CCF3)2], which does not react with any other mercury(II) salt, the compounds [(1)HgX2] react with HgX′2 (X′ = Cl, Br, I, O2CCH3, O2CPh, O2CCH2Cl) to give the insertion products [(1)Hg(μ-X′)2HgX2] only when X′ is more electron-withdrawing than X; otherwise, the addition products [(1)Hg(μ-X)2HgX′2] are formed. All reactions of [(1)HgX2] with Hg(O2CCF3)2 give the same substitution product [(1)Hg(O2CCF3)2]. The molecular structures of [(1)Hg(O2CCF3)2] and [(1)Hg(μ-Cl)2HgCl2] have been confirmed by X-ray crystallography.
