Abstract: The invention comprises ylenals, (i.e. compounds which in the same molecule contain a phosphorylene group and an aldehyde group in conjunction) of the formula where Ar is an aryl radical which may be substituted by alkyl or alkoxy groups; R1, R2 and R3 are H or alkyl groups and n is an integer from 1 to 6. They may be obtained by reacting a proton acceptor in liquid phase with a quaternary phosphonium salt of the formula where X(-) is a monovalent anion. Suitable proton acceptors are bases having a pK value below or about 9 such as alcoholates, ammonia, amines, e.g. alkylamines or heterocyclic amines, or aqueous alkali. Suitable solvents are water, dimethyl-formamide or sulphoxide, acetonitrile, alcohol, hydrocarbons, halogenated hydrocarbons or mixtures thereof. Specified products are triphenylphosphine-2-formylpropen-1-yl-1-methylene, triphenylphosphine-3-formylpropen-(2)-yl-2-methylene, triphenylphosphine-2 - methyl - 4 - formylbutadien - (1,3) - yl - 1 - methylene, triphenylphosphine-1-methyl-4-formylbutadiene - (1,3) - yl - 1 - methylene, and triphenylphosphine - 2,6 - dimethyl - 6 - formylhexatrien - (1,3,5) - yl - 1 - methylene. Examples are given for the preparation of triphenylphosphine - 2 - formylpropen - 1 - yl-methylene. The products are intermediates for the synthesis of dyes, pharmaceuticals, plant protection agents, food dyes and carolenoids. The phosphonium salts of Formula I may be obtained by reacting a suitable halogen compound with a triarylphosphine in an organic solvent.
