• Some derivatives of pseudo-geminal ketone of tris[2.2.2]paraxylylene (I) were prepared and their spectral properties were investigated in connection with their structural characteristics. The stereochemistry of two isomers of pseudo-geminal carbinols of tris[2.2.2]paraxylylene (III and V) was determined on the basis of chemical shifts of benzhydryl protons and H<SUB>o</SUB> protons in NMR spectra and also of ν<SUB>O-H</SUB> bands in IR spectra. The difference in chemical shifts of H<SUB>p</SUB> protons of the two alcohols was explained in terms of the change in electron densities of <I>para</I> carbon atoms.
