- Biocide composition and use
-
A method for the preservation of a plastics material against the growth of deteriogens which comprises treating the plastics material with a composition comprising a) an isothiazolin-3-one such as N-n-octyl- or 4,5-dichloro-N-n-octyl-isothiazolin-3-one and b) the metal complex of a thiohydroxamic acid such as 2:1 zinc complex of 3-hydroxy-4-methylthiazol-2(3H)-thione or the 2:1 zinc complex of 1-hydroxypyridine-2-thione.

- Biocidal composition and its use
-
A composition comprising a C3-5-alkyl-1,2-benzisothiazolin-3-one and the metal complex of a cyclic thiohydroxamic acid such as the 2:1 zinc salt of either 3-hydroxy-4-methylthiazol-2(3H)-thione or 1-hydroxypyridine-2-thione.

- Biocides
-
Compounds having a 5 membered, nitrogen containing ring with a thione group adjacent to a nitrogen atom substituted with an OR group have antimicrobial properties. Metal complexes or salts of these compounds also have antimicrobial properties. The compounds, or the metal complexes or salts thereof, can be used as a cutting fluid preservative, a wood preservative, in cooling water applications or as an antimicrobial agent in a paint. Some of the compounds are new. The metal complexes or salts are new.

- Cyclopentane ring formation in the cycloaddition reaction of 3-alkenyl radicals to radicophilic olefins
-
Regioselective additions of 3-alkenyl radicals (10 and 20) to electron deficient olefinic bonds (7 and 17), followed by intramolecular 5- exo-cyclization and repeated addition to radicophilic double bonds were investigated and combined into a sequence of

- The Invention of New Radical Chain Reactions. Part 9. Further Radical Chemistry of Thiohydroxamic Esters; Formation of Carbon-Carbon Bonds
-
Carbon radicals derived from the esters of several types of thiohydroxamic acids have been trapped in a number of different ways.Particular attention has been paid to carbon-carbon bond formation by addition to suitably activated ethylenic linkages.Carboxylic acids can be conveniently converted into homo- and bishomo-acids by free radical chemistry based on thiohydroxamic esters.In a coda the tautomerism of the thiohydroxamic acids have been examined by physical methods.It is confirmed that the esters used are derivatives of the thione tautomer.

- RADICAL CHEMISTRY OF THIOHYDROXAMIC ACID ESTERS
-
Thiohydroxamic esters in general decompose smoothly by a radical chain reaction to give carbon radicals which can be quenched in a synthetically useful manner.
