Abstract: Disclosed are the general principles upon which closed molecular or ionic structural frameworks may be prepared. These frameworks are based upon the self-assembly (wherein the term self-assembly refers to the association of chemical components through inter-component bonds) of n>4 subunits where surface curvature is supplied by edge sharing of subunits.

Abstract: This invention provides methods and catalyst systems for catalyzing enantioselective oxidation reactions, including cyclization reactions and enantioselective oxidation reactions of secondary alcohols and other similarly reactive organic substrates. Use of the methods and catalyst systems for kinetic resolution of racemic mixtures of secondary alcohols is also described.

Abstract: A 4-phenyl-4-oxo-2-butenoate derivative is stably supplied in a short period of time, at low cost, in high purity and on an industrial scale by a process for producing the 4-phenyl-4-oxo-2-butenoate derivative, which comprises simultaneously or continuously reacting a sulfuric ester, an aromatic hydrocarbon and a maleic anhydride derivative.

Abstract: A process for producing phenylacetic acid is provided. The process includes combining sodium, chlorobenzene, toluene, and a catalyst to form a suspension. This suspension is mixed to form phenylsodium. Upon boiling, the suspension forms benzylsodium. The suspension is then carbonized and acidified to form phenylacetic acid.

Abstract: A chiral compound, particularly a chiral secondary alcohol, can be efficiently resolved under a mild condition by acylation with an alkenyl acetate in the presence of a novel aminocyclopentadienyl ruthenium complex, an enzyme catalyst, and a base.

Abstract: There is disclosed a process for producing bisphenol A by subjecting phenol and acetone to condensation reaction in the presence of a catalyst composed of an acid type ion exchange resin which is modified in part with a sulfur-containing amine compound, wherein the ion exchange resin having a modification rate of 10 to less than 20 mol % is used for a methanol concentration in acetone of lower than 250 ppm by weight, and the ion exchange resin having a modification rate of 20 to 65 mol % is used for a methanol concentration in acetone of 250 to 8000 ppm by weight. The above process is capable of producing bisphenol A at high conversion and selectivity by suppressing deterioration of catalytic activity due to methanol as an impurity in acetone.

Abstract: The present invention provides BZPA products with improved flowability and two methods of producing such BZPA products. Both methods successfully produce BZPA products that are not prone to agglomerate upon storage, and thus the flowability of such BZPA products does not degrade over time. The first method includes mechanically forming the BZPA crystals into large compacted pellets or briquettes without the introduction of any additives or binders. The compacted pellets are large enough that the physical and chemical effects that occur on the surface of small crystal particles are eliminated or minimized, but small enough that the BZPA can be easily handled and used in commercial applications. The second method includes adding a substantially inert anti-caking agent to the BZPA crystals to minimize or retard their tendency to agglomerate. The preferred anti-caking agent is silicon dioxide (SiO2), which is blended with the BZPA crystals in small amounts.

Abstract: The present invention relates to a process for isomerizing reactant allyl alcohols to product allyl alcohols in the presence of a catalyst, wherein the reactant allyl alcohol is rearranged to product allyl alcohol in semicontinuous or continuous mode in a catalyst-containing suitable reactor. In particular, the process according to the invention is used to prepare linalool from Geraniol and/or nerol.

Abstract: The present invention provides a process for catalytic vapor phase oxidation which prevents runaway reaction or early deterioration of a catalyst, in the production of (meth)acrylic acid or the like from propylene or isobutylene by the catalytic vapor phase oxidation process using a multi-tubular reactor, which can lead to the production thereof constantly in high yield for a long period of time.

Abstract: The present invention relates to new processes for the preparation of gabapentin by the desilylation of a silylated gabapentin or by the silylation-desilylation of an acid addition salt of gabapentin with a silylating agent.
