Compounds of the formula ##STR1## wherein X is (--CR.sub.4 R.sub.4 --).sub.m in which m is 0 or 1;

Oxabicycloalkane herbicides

Intermediates for oxabicycloalkane herbicides

Certain substituted, 7-oxabicyclo[2.2.1]heptan-2-ols and -2-ones as

Certain substituted 3-cyclohexene-1-ol are intermediates to herbicides and plant growth.

Novel compounds of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are H or alkyl and R is an optionally-substituted unsaturated, cycloalkyl, secondary-alkyl, aromatic or heterocyclic group, are useful as plant growth regulators and herbicides. Certain intermediates are also novel.

6-Oxabicyclo[3.2.2]nonan-4-ol ether herbicides

Compounds of the formula ##STR1## wherein X is a single bond or --C(CH.sub.3).sub.2 ; Y is a single bond or --CH.sub.2 -with the proviso that both X and Y are not a single bond, and Z is H or alkyl; each R is H, hydroxy, oxo, methylene, alkyl or alkoxy, or one pair of adjacent R groups form a carbon-carbon bond; and R.sup.1 is H or alkyl, are useful as herbicides or plant growth regulators.

((3,4,5,6-Tetrahydro-2H-pyran-2-yl)methoxy)oxabicycloalkane herbicides

6-Oxabicyclo(3.2.2.)nonan-4-ol ether herbicides

2-exo-Hydroxy-7-oxabicyclo[2.2.1]heptanes are prepared by treating the corresponding cis-epoxycyclohexanol with acid in an inert solvent or by treating a 3-cyclohexen-1-ol which will produce the corresponding cis-epoxy alcohol successively or concurrently with an oxidizing agent and an acid in an inert solvent.

Preparation of 2-exo-Hydroxy-7-oxabicyclo[2.2.1]heptanes

Compounds of the formula ##STR1## wherein each R is H or alkyl and W is an optionally substituted unsaturated group, a cycloalkyl group, a secondary alkyl group, an aromatic group or a heterocyclic group, are useful as plant growth regulators and herbicides.

6-Oxatricyclo[3.2.1.1.sup.3,8 ]nonan-4-ol ethers and compositions and

Certain substituted tetrahydrofurans, and their use for controlling unwanted plants.

Certain herbicidal tetrahydrofurans

Novel compounds, identified in the title, useful as insecticides.

N-(arylsulfonyl)-alpha-nitro-delta .sup.2,alpha -piperidineacetamides

Certain 2-(2-halo-1-(unsaturated aliphatic))-5-nitrofurans, having activity with respect to microorganisms.
