Abstract
The synthesis of phosphino-terminated dendrimers is described up to the tenth generation, which possess more than 3000 phosphino groups (3-[G ‘ 10 ]). Several complexation reactions of these dendrimers toward various low oxidation states transition metal derivatives have been carried out, up to generation 5 for iron (4-[G ‘ 5 ]: 96 Ph2P→Fe(CO)4 groups), generation 4 for tungsten (5-[G ‘ 4 ]: 48 Ph2P→W(CO)5 groups), generation 10 for gold (6- [G ‘ 10 ]: 3072 Ph2P→Au−Cl groups), and generation 6 for rhodium (8-[G ‘ 6 ]: 192 Ph2P→Rh(acac)(CO) groups). These reactions demonstrate that the phosphino-terminated dendrimers behave analogously to monophosphines, in spite of the nanometer size of the high generations.Keywords
