Alcohols having 3-methyl or 3,5-dimethyl or 3,5-dimethylphenyl groups, a

Compounds of the general formulae ##STR1## in which R may be a methyl or ethyl radical and R.sup.1 may be a hydrogen, methyl or ethyl radical are disclosed. Also provided as part of the present invention are processes for the preparation of the above compounds. The compounds of the invention are useful as scents.

Alcohols and ethers having cyclododecyl and cyclododecenyl groups,

The invention discloses compounds of the general formula ##STR1## in which R represents a methyl radical or a methoxy radical when R.sup.1 is a hydrogen atom; or

Alcohols containing 2-methylphenyl or 2-methoxyphenyl groups, and

Compounds of the general formula (I) ##STR1## and compounds of the general formula (II) ##STR2## in which R.sup.1 represents --OH, --CH.sub.2 OH, --CH.sub.2 --OCH.sub.3, --CHOH--CH.sub.3, --CHO or --CH(OCH.sub.3).sub.2,

Aldehydes, acetals, alcohols and ethers having 3-methyl- or

This invention relates to organosiloxanes which have SiC-bonded ester groups and contain at least one unit of the general formula: ##EQU1## is which R represents the same or different monovalent hydrocarbon radicals having from 1 to 12 carbons atoms, which are free of aliphatic unsaturation and which may contain one ether oxygen atom; R' represents hydrogen or a methyl group (CH.sub.3) and a is O, 1 or 2. These organosiloxanes can be prepared by hydrolyzing or co-hydrolyzing silanes of the general formula:

Greases prepared from organosiloxanes with SiC-bonded groups

The invention relates to fungicidally active compositions that contain at least one compound of the general formula ##STR1## and/or a compound of the formula ##STR2## in which: A denotes the --CH.dbd.CH-- or --C.tbd.C-- group and R.sub.1 and R.sub.2 represent hydrogen or methyl. The active substances according to the invention can be obtained by reacting correspondingly substituted succinic acids, or acid halides, anhydrides or esters thereof, with 3,5-dichloroaniline.

2-Alkenyl and 2-alkynyl succinic acid N-(3,5-dichlorophenyl)imides

Compounds of the general formula I: ##STR1## wherein R.sub.1 and R.sub.2 are equal or different alkyl-, alkoxyalkyl-, or aryl groups, or together form a ring; R.sub.3 is an allyl or benzyl radical; and R.sub.4 and R.sub.5 represent hydrogen, alkyl, alkoxyalkyl, alkenyl or further compounds of the formula II: ##STR2## wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 have the meaning indicated above and R.sub.6 stands for hydrogen or methyl or to compounds which are modified by the addition of hydrogen to at least one olefinic or carbonylic double bond of compounds of the general formula I or II. The invention also relates to a process for preparing the new compounds. The compounds of the general formula II are obtained by thermal treatment of a selection of compounds of formula I, for which R.sub.3 stands for the allyl or methallyl radical. The compounds according to the invention are used as fragrant and flavoring substances.
