Cyclooctadienemethylplatinum complexes: synthesis, reactivity, molecular structure and spectroscopic properties of the organometallic hydroxoplatinum(II) complex [(COD)PtMe(OH)]

Organometallic complexes of the type [(COD)PtMeL] (COD= 1,5-cyclooctadiene, L=Cl, I, OH, Me, -CH2C(O)CH3, -C=C-Ph, pyridine, N-methyl-pyrazinium) and the dinuclear complex [{(COD)PtMe}(2)(mu-C=C-C=C)] were prepared and charac terised by H-1-NMR spectroscopy. The crystal structures for the complexes a with L = Cl, OH and Me are reported. The complex [(COD)PtMe(OH)] is a uniq ue example of a platinum complex containing an olefin and a hydroxy ligand on the same metal centre. It reacts with C-ET acidic substrates to form Pt- C bonds. Representative reactions with acetone, phenylacetylene and 1,3-but adiyne and the corresponding products are reported. (C) 1999 Elsevier Scien ce S.A. All rights reserved.
