Abstract: Aqueous solutions of polyenyltriarylphosphonium salts are prepared from solutions of the corresponding polyenyltriarylphosphonium salts in organic solvents by driving off the solvent with steam, part of the steam being allowed to condense. Some of the said triarylphosphonium salts may be used directly as pesticides while others are used as intermediates for organic syntheses, especially in the carotinoid field.

Abstract: Prodn. of polyenecarbonyl cpds. (I) having high all-E content, and their acetals and ketals, comprises reacting a carbonyl cpd. (II) with a dialkyl phosphonate in a Horner-Emmons reaction or with a CH-acidic cpd. in an aldol condensation in the presence of 0.3-10 mol.% (based on (II)) of a component (B) comprising a) oxygen or nitrogen monoxide (opt. mixed with an inert gas); b) the stable 2,2-diphenyl-1-picrylhydrazyl radical or a hydrogen peroxide-urea adduct; c) quinone, a quinone deriv. or coenzyme Q10 hydroquinone; and/or d) a stable radical of formula (a) or (b). R1, R2 = 1-4C alkyl; or R1+R2 = ethylene, propylene, vinylene or propenylene (all opt. substd. by alkyl, aryl, OH, alkoxy, silyloxy, oxo, NH2, SH, alkylthio, CN, COOH, carbamoyl, heteroaryl or alkylcarbonyloxy); R3-R5 = as R1, R2.

Abstract: 10-70 wt.% organic solvent solutions of polyenyl-triaryl-phosphonium salts of formula (I) (R is a 5-20C aliphatic, cycloaliphatic-aliphatic or araliphatic polyenyl residue; X is the anion equivalent of a strong acid; Ar is aryl) are converted into solvent-free aq. solutions or fine dispersions. the solvent and other steam-volatile cpds. originating from the synthesis of (I) are driven off with steam at 30-120degrees C. Part of the steam is allowed to condense so as to produce the aq. soln. or dispersion. Some cpds. (I) are useful as pesticides (e.g. against water snails), while others are intermediates, esp. for carotenoids. Aq. solns. or dispersions of (I) often preferred for organic syntheses) are easily obtd. from the organic solutions formed in the synthesis of (I).
