The present invention relates to a new process for the preparation of microcapsules based on cleavable multi-alcohols. Cleavable multi-alcohol-based microcapsules are also an object of the invention. Perfuming compositions and consumer products comprising said capsules, in particular perfumed consumer products in the form of home care or personal care products, are also part of the invention.
Four types ofO-methylated substrates were designed as probes for the detection of fingerprints of Type IV P450s.

Reaction of allylic, benzylic and tertiary alkyl halides with zinc oxide in protic solvents leads to the formation of the corresponding alcohol, ethers and esters in good yields. The scope and limitations of this reaction have been examined. The possible involvement of ion quadruplets in the reaction is suggested.
Carbon monoxide as a building block in organic synthesis. Part V. Involvement of palladium-hydride species in carbonylation reactions of monoterpenes. X-ray crystal structure of [Ph3PCH2CHCHPh]4[PdCl6][SnCl6]
A palladium precursor and SnCl2 as cocatalyst were used under 4 MPa of carbonmonoxide for the catalytic alkoxycarbonylation of several monoterpenes into C11 esters. The active catalyst involves a palladium-hydride species whose formation was investigated. In the case of the model substrate 3-phenylpropene, the source of the hydrido ligand was determined to be the alkene itself. Allylic hydrogen abstraction
