Abstract: Process for producing organic tertiary polyphosphine monooxides which comprises reacting an organic tertiary polyphosphine with an organic monofunctional alkylating agent to form an intermediate monophosphonium salt of the polyphosphine starting material and then hydrolyzing the salt so produced to the desired polyphosphine monooxide product.

Abstract: Metal or metalloid salts, ansolvo-acids and proton-acids can be so complexed with 1,2,3-triols, glycerol ethers or glycerol thioethers containing at least 6 C atoms in the molecule that they are in the form of compositions which are soluble in organic solvents, especially non-polar, aprotic solvents, such as hydrocarbons. These stable compositions display an outstanding anti-static action and, because of their spectrum of properties, are especially suitable for imparting anti-static characteristics to polymers, lubricants, fuels and also solvents based on hydrocarbons.

Abstract: New derivatives of 8-dehydro-vitamin A obtained by vinylating or ethynylating and subsequently partially hydrogenating, 1-[3-methyl-octa-1-yne,3,5,-dien-7-on-1-yl]-2,6-dimethyl-cyclohex-1-ene or its 5- and/or 6-methyl derivatives, converting the resulting alcohols to the corresponding derivatives of 8-dehydro-vitamin A halides by reacting with thionyl chloride or phosgene, and if required converting the resulting alcohols or halides to the corresponding trialkylphosphonium salts or triarylphosphonium salts, or reacting the 8-dehydro-vitamin A halide derivatives with alkali metal salts or alkaline earth metal salts or anhydrides of lower carboxylic acids. The new compounds can be partially hydrogenated to the corresponding polyene compounds, in which case the cis-trans isomer mixtures first obtained can be rearranged in the conventional manner to the physiologically active all-trans compounds.

Abstract: Tri(phenyl)alkyl phosphonium halides wherein the phenyl groups contain a long chain or sterically hindered alkyl group are novel and exhibit efficacious levels of fungicidal and bacteriocidal activity. The presence of the alkyl substituent eliminates or significantly reduces the phytotoxicity that characterizes the corresponding unsubstituted phosphonium compounds.
