Abstract :
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=η5-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 1H-, 13C{1H}-, and 29Si{1H}-NMR spectroscopy, elemental analysis, and (except for Ti dendrimers) MALDI-TOF mass spectroscopy.
