Abstract
The first dendrimers containing metallacarborane modules have been prepared and characterized. The acyl derivative nido-[η5-C5H4C(O)Cl]Co(2,3-Et2 C2B3H5) was treated with diaminobutane-dend-(NH2)16 (DAB-16) and Et3N in CH2Cl2 to give the 16-and 32-cobalt metallodendrimers DAB-dend-NHC(O)-C5H4Co(2,3-Et2B 3H5)]16 (5) and DAB-dend-[NHC(O)-C5H4Co(2,3-Et2C2 B3H5)32 (6), which were isolated as air-stable yellow solids in 76% and 79% yields, respectively.
