    • Control and repellency of biting flies, house flies, ticks, ants, fleas, biting midges, cockroaches, spiders and stink bugs is obtained by contact of the insects with at least one of the compounds of the structure (I) wherein R is —OH, ═O, —OC(O)R4, —OR6, or —(OR6)2, wherein each R6 is independently an alkyl group containing from 1 to 4 carbon atoms and R4 is a branched or straight chain, saturated or unsaturated, hydrocarbyl group with zero to two double bonds and from 1 to 15 carbon atoms; X is O or CH2, with the proviso that when X is O R can only be ═O: each Z is independently (CH) or (CH2); y is a numeral selected from 1 and 2; R1 is H or a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to two double bonds and from 1 to 15 carbon atoms; R2 is H and a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to three double bonds and from 1 to 15 carbon atoms; R3 is H, a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to three double bonds and from 1 to 15 carbon atoms, —(CH2)nOH, —C(O)OR5, —CH2C(O)OR7, —CH2C(O)R8, —C(O)NR9R10, or —CH2C(O)NR11R12 where each of R5, R7, R8, R9, R10, R11 and R12 is independently H or a branched or straight chain, saturated or unsaturated hydrocarbyl group with zero to three double bonds and from 1 to 15 carbon atoms, and n is n integer of from 1 to 12; the bond between the 2 and 3 positions in the ring structure may be a single or a double bond; and wherein the compounds of structure (I) contain from 11 to 20 carbon atoms except where R is ═O, X═CH2 and y is 1 the compounds of structure (I) contain from 13 to 20 carbon atoms, with the proviso that when R3 is —CH2C(O)OR7 R1 and R2 must be H or a saturated hydrocarbyl group with zero double bonds. The invention also includes optical isomers, diastereomers and enantiomers of the compounds of structure (I).

    • The invention concerns Diels-Alder reactions between non-activated aldehydes RCHO in which R is a C1-C10 aliphatic group or phenyl group, which is unsubstituted or substituted with one or more C1-C5 alkyl groups or one other functional group, with simple aliphatic dienes R.sub.1 CH.dbd.CR.sub.2 --CR.sub.3 .dbd.CHR.sub.4 in which R.sub.1 -R.sub.4 are H or C1-C5 alkyl groups using as a catalyst a perfluorinated organic sulphonic acid or a Bronsted acid derivative thereof. The reaction leads to dihydropyrans of the structure below in which R1-R4 have the meaning indicated above.The preferred perfluorinated organic sulfonic acids are perfluorooctanesulphonic acid, triflic acid, Nafion or a Bronsted acid derivative of triflic acid. ##STR1## The preferred aldehydes are those wherein R is a C2-C6 aliphatic group or a phenyl group which is unsubstituted or mono-substituted with C1-C3 alkyl or with 4-Cl, 4-nitro or 3-methoxy. The preferred dienes are those wherein the groups R.sub.1 -R.sub.4 are H or methyl.
