Solid state oxidative deprotection of trimethylsilyl ethers with iron (III) nitrate and montmorillonite under microwave irradiation

Mixture of iron (III) nitrate and montmorillonite K10 oxidatively deprotect trimethylsilyl ethers to their corresponding carbonyl compounds under microwave irradiation in solventless system, in a short time and good yields.

IMPROVEMENTS IN OR RELATING TO ORGANIC COMPOUNDS

Disclosed is a compound represented by formula (I). The half-doted double lines each represent a carbon-carbon single bond or a carbon-carbon double bond. The six-membered ring comprises exactly one endocyclic carbon-carbon double bond or exactly two endocyclic carbon-carbon double bonds. When the six-membered ring comprises exactly two endocyclic carbon-carbon double bonds, the endocyclic carbon-carbon double bonds are either in 1,3-relationship or in 1,4-relationship. R is selected from the group consisting of iso-propyl, iso-butyl, sec-butyl and tert-butyl.

CYCLOHEXENE DERIVATIVES AS PERFUMING INGREDIENTS

The present invention concerns a compound of formula (I) in the form of any one of its stereoisomers or a mixture thereof, and wherein n is 0 or 1; R and R', independently from each other, represent a hydrogen atom or a C1-2 linear alkyl group provided that one of said groups represents a hydrogen atom and the other a C1-2 linear alkyl group; each R1, independently from each other, represents a hydrogen atom or a methyl group; and R2 and R3 represent, independently of each other, a C1-3 linear alkyl group; or R2 and R3, when taken together, represent a C4-5 linear, branched alkanediyl or alkenediyl. The use of compound of formula (I) as perfuming ingredients of floral type and the invention's compounds as part of a perfuming composition or of a perfuming consumer product are also part of the present invention.

Efficient and practical solvent-free oxidation of alcohols using microwave irradiation

Alcohols are oxidised rapidly to the corresponding carbonyl compounds by montmorillonite KSF or silica supported barium manganate, under solvent-free conditions and microwave irradiation.
