| Abstract: | Summary The complex Pd(dpmMe)2]Cl2 dpmMe = 1,1-bis-(diphenylphosphino) ethane] was prepared from PdCl2-(PhCN)2], whilst Pd2X2( -dpmMe)2] complexes were prepared from PdCl2PhCN2] and Pd(PPh3)4] (X = Cl), PdBr(
3-C3H5)]2 (X = Br), or Pd2Cl2(-dpmMe)2] (X = I). Reaction of Pd2Cl2(-dpmMe)2] with MeO2C-C523-01CCO2Me(L) gave the A-frame complex PdCl2(-L) (-dpmMe)2]. The complexes PtCl2(dpmMe)] and Pt(dpmMe)2]Cl2 were prepared from PtCl2(Bu
t
CN)2]. Treatment of either PtCl2(dpmMe)] with PhC523-02CLi or Pt(dpmMe)2]Cl2 with MeONa gave Pt(Ph2PCMe· PPh2)2]. Reaction of PtCl2(Bu
t
CN)2] with Pt(PPh3)4] and dpmMe gave a mixture of Pt2Cl2(-dpmMe)2] and PtCl2(dpmMe)]. The heterobimetallic complexes Pt(C523-03CPh)2 (-dpmMe)2MX] (MX = HgCl2 or AgCl) were made from the reaction of Pt(dpmMe)2]Cl2 with Hg(C523-04CPh)2 or Ag(C523-05CPh), respectively. Reaction of the Pt-Hg complex with Na2S gave Pt(C523-06CPh)2 (
1-dpmMe)2]. Oxidative addition of MeI to PtMe2· (dpmMe)] gave two PtIV isomers of the formula PtMe3I(dpmMe)]. |
