Abstract
Abstract Molybdenum compounds, particularly molybdenum sulfide, molybdenum silicide, molybdenum selenide and molybdenum telluride are useful Friedel-Crafts catalysts for the aralkylation of aromatics to produce polybenzyls, the manufacture of aromatic ketones, aromatic sulfones and aromatic esters. The foregoing processes are carried out at a temperature of about 60° to 250° C. and at a catalyst concentration of about 0.1 to 15% by weight of reactants. The reaction products are useful as laminates, herbicides and bactericides.
