*Yields were determined by 1H NMR using CH2Br2 as the internal standard. wIsolated yield in parenthesis. z1.0 equiv. Ag2CO3 was used. 76% isolated yield (entry 11). It is worth noting that the alkoxycarbonylation reaction was quite sensitive to the amount of Ag2CO3. Attempts to lower...
traces of isomers were observed for some substrates. However, it was hard to assign the peaks of isomers that were only traces from the crude 1H NMR and thus we did not attempt to calculate the exact ratios of isomers. Finally, the template-directing group could be removed and recycled ...
The interpretation of this structure was further enhanced by IR, NMR (1H, 13C, 119Sn) and 119mSn Mössbauer experiments. 展开 关键词: Triphenyltin Carboxylates 5-[(E)-2-(Aryl)-1-diazenyl]-2-hydroxybenzoic acids Crystal structure
