EFFECT OF CARBOXYLIC ACIDS ON THE METATHESIS OF METHYL 10-UNDECENOATE.

The metathesis of esters of unsaturated carboxylic acids catalyzed by the WCl//6/Me//4Sn system is influenced by the presence of free acids. The extent of their effect depends on how they are delivered into the reaction mixture. If the acid is allowed to

The Reactivity of Molybdenum and Tugsten Trioxide Vapours towards Organic and Inorganic Compounds at -196 deg C

Vapours of molybdenum and tungsten trioxides, prepared by heating the solid oxides under vacuum, have been reacted with organic compounds and some inorganic halides at -196 deg C.Complexes of the trioxides are formed with pentane-2,4-dione, acetone, formic acid, and methanol, but the oxides fail to bring about metathesis or isomerisation of olefins.Oxygen-halogen exchange reactions occur between the trioxides and BCl3, SiCl4, and HCl; PCl3 is oxidised.The reactivity of the condensed vapours of both oxides at -196 deg C is markedly higher than the reactivity of the normal solid oxides at room temperature.
