The synthesis of a novel class of fluorous ionic liquids was investigated. The 2,6‐diperfluoroalkyl‐substituted pyridinium salts 2b‐f were solids at ambient temperature and insoluble in perfluoromethylcyclohexane. The addition of much further fluorous alkyl group to nitrogen atom of 2,6‐disubstituted pyridines 1 did not proceed to afford the pyridinium salts 3 having two or three perfluoroalkyl groups...
The stereoselective synthesis of 1,2,3‐triol derivatives having contiguous stereogenic centers from α,β‐unsaturated acylsilanes 1 was described. The oxidation of an olefin moiety of 1 with osmium tetroxide proceeded smoothly to give the corresponding 2,3‐syn‐dihydroxyacylsilanes 2. The protection of two hydroxy groups of 2 followed by a nucleophilic reaction to the silyl carbonyl group gave the corresponding...
