An effective preparation of both 1,3-diketones and nitriles from alkynones with oximes as hydroxide sources

An effective phosphine-catalyzed protocol has been established for the syntheses of 1,3-diketones and nitriles from alkynones with oximes as hydroxide surrogates. This method features the use of a phosphine catalyst, compatibility with various functional groups and ambient temperature, which makes this approach very practical. A plausible mechanism was proposed.

PARTICULATE UV PROTECTION AGENT

The present invention relates to particulate UV protection agents which are obtainable by hydrothermal treatment of a particulate metal oxide and subsequent application of a manganese oxide coating, and to the preparation and use thereof. The present invention furthermore relates to novel compositions, in particular for topical application, which are intended, in particular, for light protection of the skin and/or hair against UV radiation and free-radical-induced stress, and to the use thereof in the above-mentioned cosmetic application.

Cosmetic compositions comprising photostabilized dibenzoylmethane compounds and 2-pyrrolidinone-4- carboxy esters

Photostable cosmetic compositions contain, formulated into a cosmetically acceptable vehicle, at least one UV-screening system that includes: (a) at least one dibenzoylmethane compound, and(b) at least one 2-pyrrolidinone-4-carboxy ester compound having the following formula (I): in which: R1 is a linear or branched C1-C20 alkyl radical, andR2 is a linear or branched C1-C20 alkyl radical which optionally includes a C5-C6 ring member, the phenyl radical, the benzyl radical or the phenethyl radical.
