Corner-opening and corner-capping of mono-substituted T8 POSS: product distribution and isomerization

We applied chromatographic and spectroscopic techniques to revisit the product distribution of the corner-opening and corner-capping reactions of monosubstituted T8 POSS. The monosubstituted Si is more likely to be removed than the remaining seven Si atoms during the corner-opening. After the corner...

description We applied chromatographic and spectroscopic techniques to revisit the product distribution of the corner-opening and corner-capping reactions of monosubstituted T8 POSS. The monosubstituted Si is more likely to be removed than the remaining seven Si atoms during the corner-opening. After the corner-capping, the yield of monosubstituted T8 POSS is much higher than the yields of the ortho- and meta-isomers of disubstituted T8 POSS, and the para-isomer is negligible.
