Xylyl group

Xylene - Wikipedi

Xylene (from Greek ξύλο, xylo, wood), xylol or dimethylbenzene is any one of three isomers of dimethylbenzene, or a combination thereof. With the formula (CH 3) 2 C 6 H 4, each of the three compounds has a central benzene ring with two methyl groups attached at substituents.They are all colorless, flammable liquids, some of which are of great industrial value These PMOs have an ordered hexagonal channel mesostructure, some degree of ordering of aromatic groups likely through π-π stacking in the channel walls, a large pore volume and surface area, and relatively thick arylsilica walls whose dimensions seem to scale with the spatial demands of the aryl group An O-Xylyl Diol Protecting Group A.

Smyth Department of Chemistry , SUNY at Buffalo , Buffalo, NY, 14214 Pages 3363-336 A new protecting group for alcohols, the p-trimethylsilyl xylyl (TIX) group has been developed.The TIX group is used to protect various alcohols under acidic as well as basic conditions. The protected ethers thus formed had noteworthy chemoselectivity upon deprotection in the presence of other benzyl ethers and commonly used protecting groups

  4. The dipole is due to the CH 3 group's tendency to push electrons away from itself. This also affects the reactivity of methylbenzene (see below). Melting points. You might have expected that methylbenzene's melting point would be higher than benzene's as well, but it isn't - it is much lower! Benzene melts at 5.5°C; methylbenzene at -95°C
