In the last 3-4 years, this has been a rapidly growing field in organic chemistry, and many papers have appeared reporting excellent protocols for carrying out these highly efficient transformations that compete well with other classical approaches using transition metal catalysts.

Thermotropic liquid crystals react to changes in temperature or, in some cases, pressure. The reaction of lyotropic liquid crystals, which are used in the manufacture of soaps and detergents, depends on the type of solvent they are mixed with. Since the accidental discovery of the chiral nematic (ordered) phase in 1888 many liquid crystal phases have been found, sometimes by chance and sometimes by design. The existence of one such phase was predicted by Freiser in 197 606 $aNematic liquid crystals 606 $aLiquid crystals$xSpectra 606 $aLiquid crystals$xResearch 615 0$aNematic liquid crystals. 615 0$aLiquid crystals$xSpectra. 615 0$aLiquid crystals$xResearch. 676 $a530.4/29 702 $aLuckhurst$b G.
