C. Eychennebaron et al., NEW SYNTHESIS OF THE NANOBUILDING BLOCK USN)(12)O-14(OH)(6))(2-14(OH)(6))(O3SC6H4CH3)(2)() AND EXCHANGE PROPERTIES OF ((BUSN)(12)O), Journal of organometallic chemistry, 567(1-2), 1998, pp. 137-142
This paper deals with a new and easy way to synthesize the macrocation
{(BuSn)(12)O-14(OH)(6)}(2+) from BuSnO(OH) and p-toluene sulfonic aci
d. It was isolated by crystallization as {(BuSn)(12)O-14(OH)(6)}(O3SC6
H4CH3)(2)C4H8O2. Exchange properties of sulfonates with different anio
ns have been studied in several solvents by using Sn-119- and H-1-NMR.
Sulfonate anions can be exchange in isopropanol by acetate or hydroxy
l groups by reaction with sodium acetate or tetramethylammonium hydrox
ide, respectively. (C) 1998 Elsevier Science S.A. All rights reserved.
