straightforward synthesis of various imides from olefins and CO for the first time. The established hydroamidocarbonylation reaction affords imides in good yields (up to 90 %) and with good regioselectivity (up to 99:1) when applying different alkenes and amides. The synthetic potential of the method is highlighted by the synthesis of Aniracetam by intramolecular hydroamidocarbonylation.
Perfume delivery systems, comprising insoluble carrier particles with surface silanols, which have been grafted with an organosilane and which carry organic residues with a positively charged functional group and a fragrance adsorbed to or absorbed into the carrier particles. The perfume delivery systems impart a long lasting fragrance to fabric treated with compositions containing the perfume delivery system.
