Abstract: A polycyclic compound of general formula (I): R - X - [A - X ] - [A - X ] - R (=wherein R is C6-C16 (halo)alkyl; X is -O- or a single bond; A is biphenylene, phenylene or the like; A is 1-fluoro-3,4-dihydronaphthalene or the like; X and X are each -COO-, a single bond or the like; and R is an optically active group having at least one asymmetric carbon atom and 4 to 20 carbon atoms); a liquid-crystal material composed of the above polycyclic compound; and a liquid-crystal composition and a liquid-crystal device containing the material. This novel polycyclic compound is optically active, exhibits a smectic phase over a wide temperature range including room temperatures, and can be used as a ferroelectric or antiferroelectric liquid-crystal material. The use of the liquid-crystal material makes it possible to produce a liquid-crystal device exhibiting a rapid response over a wide temperature range.

Abstract: A method for producing aryl alkyl hydroperoxides which comprises selectively oxidizing an aryl alkyl hydrocarbon having the formula: wherein P and Q are hydrogen or an alkyl and may be the same or different from each other; x is an integer of 1-3; and Ar is an aromatic hydrocarbon group having a valence of x, with an oxygen-containing gas in the presence of a transition metal complex which contains, as a ligand, a cyclic polyfunctional amine compound having at least three nitrogen atoms in the ring forming molecular chain or an open chain polyfunctional amine compound having at least three nitrogen atoms in the main chain of the molecule.
