The invention relates to novel pesticidally active compounds of the general formula I as well as possible isomers and mixtures of isomers thereof, wherein n is a number zero or one; and R1is C1-C12alkyl that is unsubstituted or may be substituted by C1-C4alkoxy, C1-C4alkylthio, C1-C4alkylsulfonyl, C3-C8cycloalkyl, cyano, C1C6alkoxycarbonyl, C3-C6alkenyloxycarbonyl or by C3-C6alkynyloxycarbonyl; C3-C8cycloalkyl; C2-C12alkenyl; C2-C12alkynyl; C1-C12haloalkyl: or a group NR11R12wherein R11and R12are each independently of the other hydrogen or C1-C8alkyl, or together are tetra- or penta-methylene; R2and R3are each independently of the other hydrogen; C1-C8alkyl; C1-C8alkyl substituted by hydroxy, C1-C4alkoxy, mercapto or by C1-C4alkylthio; C3-C8alkenyl; C3-C8alkynyl; C3-C8cycloalkyl; C3-C8cycloalkyl-C1-C4alkyl; or the two groups R2and R3together with the carbon atom to which they are bonded form a three- to eight-membered ring; R4, R5, R6and R7are identical or different and are each independently of the others hydrogen or C1-C4alkyl; R8is C1-C6alkyl, C3-C6alkenyl or C3-C6alkynyl; A is C1-C6alkylene; and B is optionally mono- or poly-nuclear, unsubstituted or substituted aryl; optionally mono- or poly-nuclear, unsubstituted or substituted heteroaryl; C4-C12alkyl; or C3-C8cycloalkyl. The novel compounds have plant-protecting properties and are suitable for protecting plants against infestation by phytopathogenic microorganisms.

- Process for the production of 3,4-dideoxyhexitol
-
A process for the production of 3,4-dideoxyhexitol and for its cyclodehydration to 2,5-bis(hydroxymethyl)tetrahydrofuran. The 3,4-dideoxyhexitol is obtained by hydrogenolysis in the presence of a copper chromite catalyst, of hexitols, or of compound which undergo reaction with hydrogen to give hexitols.

- Oxidation of Copper in Nitrogen Dioxide
-
Thermal microgravimetry, mass spectrometry, and X-ray diffractometry were used to investigate the ability of NO2 to oxidize copper.NO2 oxidizes a copper plate with formation of oxide film consisting of Cu2O (predominant) and CuO.The oxidation obeys a cubic law, and proceeds faster than in oxygen.An oxidation mechanism is presented on the basis of kinetic and structural data.
