the synthesis of primary amides has long been an elusive aim. Here, we report an efficient catalytic system which enables inexpensive NH4Cl to be utilized as a practical alternative to gaseous ammonia for the palladium-catalyzed alkene-hydroaminocarbonylation reaction. Through appropriate choice of the palladium precursors and ligands, either branched or linear primary amides can be obtained in good

The invention relates to the use of compounds of the phenoxyalkylamine family of formula (I) in cosmetic and/or dermatological compositions, especially as preserving agents. The invention also relates to compositions comprising, especially as preserving agent, at least one phenoxyalkylamine of formula (I). The invention also relates to particular compounds of the phenoxyalkylamine family of formula (I) and to cosmetic and/or dermatological compositions containing them.
The present invention relates to silica-filled rubber compositions containing dialkyleneamide polysulfides of the formula
where R1 is independently selected from alkylene groups having 1 to 18 carbon atoms and x is an integer of from 2 to 7.
