Abstract
Organometallic polymers containing Pd atoms in different co-ordination sites were obtained and characterized. The reactions were performed i n a wide range of complex/monomer molar ratios. Functionalized monosub stituted acetylenes, namely propargyl alcohol (POH) and N,N-dimethylpr opargylamine (DMPA) undergo coordinative polymerization in the presenc e of the corresponding bis(triphenylphosphine)bis(acetylide) Pd(II) co mplexes, [Pd(PPh3)(2)(C=C-CH2OH)(2)] and [Pd(PPh3)(2)(C=C-CH2N (CH3)(2 ))(2)]. The complexes are active catalysts for the activation of the C -C bond of acetylenic monomers, leading to a pi-conjugated C=C backbon e. By increasing the complex/monomer ratios, interaction of Pd with th e C=C double bonds of neighbour chains and with the polymer pendant gr oups also occurs. (C) 1997 Elsevier Science Ltd.
