wehrein
(i) R, is a group -X-CO-CH3 where X is a hydrocarbon radical having up to 4 carbon atoms which may be substituted by a methyl group. R2 and R3. which may be the same or different, each represents a straight-chain or branched-chain alkyl radical of 2 to 6 carbon atoms, or a cyclohexyl, alkoxyalkyl or hydroxyalkyl radical, and Y and Z each represent oxygen;
(ii) R, is a group -CH2(OR4)(OR5)CH3 wherein R4 is an alkyl radical of 1 to 4 carbon atoms and R, is an alkyl radical of 1 to 4 carbon atoms or R4 is linked to R5 so that the OR. and OR5 moieties and the carbon atoms to which they are attached form a 1,3-dioxacyclohexa-2,2-diyl,1,3-dioxacyclo- penta-2,2-diyl or 1,3-dioxacyclohepta-2,2-diyl diradical, R2 and R3 are the same or different and are each an alkyl radical of 1 to 4 carbon atoms, and Y and Z each represent oxygen;
(iii) R' is a group -CH2COCH3 R2 is an alkyl radical of 1 to 6 carbon atoms, R3 is an alkyl radical of 1 to 6 carbon atoms, Z is sulphur and Y is oxygen or sulphur;
(iv) R, is a group -(CH2)nCOCH3 where n is 1 or 2, one of R2 and R3 is an alkyl radical of 1 to 6 carbon atoms and the other is an alkyl radical of 2 to 6 carbon atoms, Z is oxygen and Y is sulphur; or
(v) R, is a group -CHZCOCH3 R2 is an alkyl radical of 1 to 4 carbon atoms, R3 is a group CH3CO(CH2)4 -, and Y and Z each represent oxygen.
