The present application relates to encapsulates, compositions, products comprising such encapsulates, and processes for making and using such encapsulates. Such encapsulates comprise a core comprising a perfume and a shell that encapsulates said core, such encapsulates may optionally comprise a parametric balancing agent, such shell comprising one or more azobenzene moieties.
Palladium‐catalyzedcross‐coupling reactions between carboxylic acids and arylhalides have several possible competitive pathways. Decarboxylative C−C bond coupling and C−H arylation are well established in the literature. However, direct C−O bond coupling between carboxylic acids and arylhalides has received little success. In this report, we describe a protocol for exclusive C−O bond formation,

group and ferroceneboronic acid at the carbonyl group catalyzed with various N-heterocyclic carbenes afforded the corresponding ferrocenyl esters. In these reactions copper(II) sulfate, cinnamic aldehyde, and air oxygen act as oxidants. The resulting ferrocenyl esters of vanillic acid were tested for cytotoxicity.
