Reactions of (CH3)3SiRf (Rf = CF3, C2F5) with NOCl, NO/NO2, SO2, CO2, in the presence of caesium fluoride provide a one step synthetic route to perfluoroalkylated compounds in very good yields.

Pyridine-2,6-dimethanol, C7H9NO2, forms a chain structure in which the molecules are linked by O--H..-O hydrogen bonds into dimeric units lying across centres of inversion, these dimers being linked by O---H...N hydrogen bonds into chains around other centres of inversion. In the structure of benzene-l,3,5-trimethanol, C9HI203, the molecules form a continuous three-dimensional network in which each molecule is hydrogen-bonded to six others.
