摘要： Anthralin analogues containing a thio-substituent, especially in one or more of the positions 2-, 7- and 10- of the anthralin ring. They may be made by reacting an anthralin derivative (e.g. 10-bromoanthralin) with a thiol or a compound containing a group convertible to a thio-group. Alternatively, a 1,8-dihydroxy anthraquinone containing a thio-substituent may be reduced. Reactive intermediates may be made by introducing one or more nuclear allylic groups into a 1,8-dihydroxy anthraquinone and then converting them into a reactive form, e.g. by epoxidation or halide addition. The intermediate can then reduced to the oxidation state corresponding to anthralin.Additional products having the 10-carbon atom of the anthralin ring as part of a heterocyclic ring, may be made by anthralins containing various substitutes thioalkyl groups as the 10-substituent.The compounds are useful for treatment of psoriasis, and may be formulated in the conventional vehicles for topical application, for example petrolatum.

摘要： The hydroformylation of olefins with rhodium complex catalysts is described. The catalysts employed comprise a rhodium complex with at least one phosphine having a specified structure, e.g., tris(benzyl)phosphine. Preferred phosphines have a pKa in the range of about 3.5 up to 5.3 and a cone angle in the range of about 160 up to 195.degree.. Hydroformylation reactions at relatively low temperatures and pressure and yet with high rates of reaction and high selectivity to aldehyde product are obtained by the practice of the present invention.

摘要： Benzoin esters of aromatic sulfonic acids can be obtained in high yield from benzoin and the respective sulfonyl halide in molar amounts of a base by carrying out the reaction at low temperature in an organic solvent with the addition of water. Aqueous NaOh or KOH can be used as base in this process.
