Large dendrimers, noted Gn-3n+2cage, containing 3n+2o-carborane cluster cages MeC2B10H 10at their peripheries (n = number of generation noted Gn) have been synthesized by Huisgen

Several strategies have been used to functionalize 1,3,5-trisubstituted arene-cored dendrimers with the organometallic electron-reservoir moiety [Fe(η5-C5H5)(η6-C 6Me6)]+, 1, to provide dendritic multielectron reservoirs. They all start from the carboxylic acid [Fe(η5-C 5H4COOH)(η6-C6Me 6)][PF6], 2, or its acyl chloride derivative [Fe(η5-C5H4COCl)(η6-C 6Me6)][PF6], 3. For this purpose, a series of new polyamine dendrimers from G0 to G2 with 1→ 3 C connectivity of the branching to the core have been synthesized. Amide, "click" and ionic ammonium carboxylate linkage successfully provided G0, G1, and G2 metallodendrimers with 9, 27, and 81 cationic terminal organoiron groups respectively. Further construction of large metallodendrimers up to G7 with approximately 14 000 organoiron termini was only possible by combining amide, "click", and tether lengthening strategies to avoid steric bulk at the dendrimer periphery. Reduction of the 18-electron FeII metallodendrimers, exemplified by a G4-DAB-64-FeII complex, was achieved exergonically using the parent electron-reservoir complex [Fe(η5-C5H 5)(η6-C6Me6)], 1a, at ?30 °C in MeCN, which allowed further reduction of 64 equiv of C60 to C60·? using the 19-electron FeI metallodendrimer.

In the quest for general and efficient synthetic procedures for dendrons and dendrimers, allylphenol, allylnaphthol and 6-bromonaphthalene AB3 dendrons have been successfully prepared on a large-scale by a rapid and clean route starting from commercially available esters and allyl bromide. In contrast to the known organoiron strategy, the above-mentioned methodology enables the large-scale synthesis of AB3 dendrons in only two days.
Activation of aryl ethers and aryl sulfides by the Fe(η5-C5H5)+ group for the synthesis of phenol dendrons and arene-centered poly-olefin dendrimers

Organo-iron mediated syntheses of dendrons and dendrimers are described. The reaction of [FeCp(η6-p-EtOC6H4Me)][PF6], 1, with Bu(t)OK or KOH and allyl bromide in THF gives both the triallylation of the acidic Me
