摘要：

Hydrosilylation of 4-allyl-2-methoxyphenol (eugenol) with silane dendrimers of first or second generation and -SiMe2H ending groups affords new dendrimers with -SiMe2(CH2)(3)(C6H3(OMe)(OH)) terminating groups. The reaction of the hidroxy functionalities of these dendrimers with [CpTiCl3] (Cp = eta(5)-C5H5) provides an effective route for the attachment of cyclopentadienyl titanium complexes to the dendritic periphery. The yields of the prepared dendrimers with -SiMe2(CH2)(3)(C6H3(OMe)(OTiCl2Cp)) terminating groups are near quantitative. All the dendrimers are characterised by H-1-,C-13(H-1)-, and Si-29(H-1)-NMR spectroscopy, elemental analysis, and (except for Ti dendrimers) MALDI-TOF mass spectroscopy.
