Abstract: An aldehyde (R.sup.1 CHO) and optically active 3-hydroxybutyric acid (CH.sub.3 CH(OH)CH.sub.2 COOH) are reacted to form an optically active dioxanone. This dioxanone is reacted with a compound R.sup.2 --X to form an intermediate (R.sup.1 R.sup.2 CHOCH(CH.sub.3) CH.sub.2 COOH) which is then subjected to elimination to form an optically active secondary alcohol (R.sup.1 R.sup.2 CHOH) in good yield and purity.
Abstract: A method for the manufacture of dimethyl octyl (or pentyl) para-amino benzoic acid is described. The method consists in the carbonylation of para-bromo-dimethyl aniline, in the absence of any promoter, in a reaction system having a pH of above 8 in the presence of an alcohol selected from octanol, pentanol or isomers thereof using a palladium catalyst on an inert support. The reaction is carried out at a temperature in the range of 140.degree. to 200.degree. C. and a pressure of between 1 to 5 atmospheres. The product obtained is characterized by its high purity being substantially free of any impurities.
Abstract: Disclosed is a process for the oxidation of 4,4'-diisopropylbiphenyl which gives an excellent ratio of dihydroperoxide to monohydroperoxide and a low amount of other oxygenated compounds. The dihydroperoxide can be converted, by known procedures, to 4,4'-biphenyldiol or a diester thereof which are valuable monomers used in the manufacture of high performance polyesters. Certain of the disclosed compounds such as the dihydroperoxide, monohydroperoxides and diesters are new compositions of matter.

Abstract: 2-Methallyloxyphenol is produced selectively in good yield, high purity and without having to separate and recycle large amounts of catechol, in the reaction of methallyl chloride with catechol, by forming a substantially non-aqueous mixture of an alkali metal catecholate and a molar excess of methallyl chloride perferably in a polar organic solvent in which the methallyl chloride is substantially insoluble, agitating the mixture to produce a two-phase system comprising an organic first phase containing product 2-methallyloxyphenol dissolved in methallyl chloride and a polar second phase containing unreacted catecholate, and recovering product 2-methallyloxyphenol from the first plase. The presence of a quaternary ammonium or phosphonium catalyst in the reaction mixture further reduces undesired ring-alkylated by-products.
