Chloride and Co

Palladium-catalyzed oxidation of hydrocarbons has been a matter of intense research for about four decades. The field was initiated by the development of the aerobic oxidation of ethylene to acetaldehyde catalyzed by palladium chloride and co-catalyzed by cupric chloride (the Wacker process, equation l)1. [Pg.653]

The ester acid chlorides used in these preparations, w-car-bethoxyvaleryl chloride and co-carbethoxynonanoyl chloride, were obtained from the corresponding half esters in yields of 90-95%. The method described for /3-naphthoyl chloride was used, but since with these acids the reaction is much more vigorous the phosphorus pentachloride was added in small portions and the mixture was not heated until after the exothermic reaction had subsided. [Pg.79]

Adding phosphoric acid sometimes improves the yield. According to Wey-gand a mixture of benzyl chloride and co,co-dichloroxylene is obtained as follows ... [Pg.953]

This Pd-catalyzed transformation uses two imines an acid chloride and CO. Mechanistically, this reaction is proposed to proceed via Pd addition to the activated imine, followed by CO insertion. Reductive elimination of Pd with HCl provides the ketene, which undergoes formation of the Munchnone. Miinchnones are known to undergo cycloaddition reactions with electron-deficient imines to yield cycloaddition adducts, which lose CO2 and TsH to yield imidazole. [Pg.352]

In our investigation, we attempted to produce an emulsion system having no such defects by using water alone as solvent. Mario, et al. ) tried to prepare a "water in water" emulsion by mixing three water soluble poljmier solutions, [poly (oxyethylene), poly (2-vinylpyridinium chloride) and co-poly (2-vinyl pyridinium chloride)-poly (oxyethylene)] and developed a comparatively stable system. [Pg.576]

Separate the layers and determine which is the organic layer. Wash the organic layer sequentially with 10-mL portions of saturated aqueous sodium chloride and co/d saturated aqueous sodium bicarbonate. On initial addition of the bicarbonate solution, vigorous gas evolution will normally occur gently swirl the unstoppered separatory funnel until this stops. Stopper the funnel and carefully... [Pg.475]

Analogously, o-cresol is obtained from crotyl chloride and m-cresol from methallyl chloride, whereas phenylacetylene, methallyl chloride and CO yield 2-phenyl-m-cresol. Propyne, allyl chloride and CO react to give o-cresol [680, 799]. [Pg.170]

Form Supplied in pale yellow crystals widely available. Analysis of Reagent Purity IR MS NMR H NMR. Preparative Methods numerous routes are available. Preferred methods are reaction of propene with palladium(II) trifluoro-acetate, followed by counterion exchange with chloride reaction of potassium tetrachloropalladate(II) with allyl chloride in water reaction of Na2PdCl4, allyl chloride, and CO in water. ... [Pg.42]
