The inÑuence of the acidity of ultrastable Y (USY) zeolite-supported tungsten or nickel sulÐde catalysts, prepared at di †erent pH values, on thiophene hydrodesulfurization activity has been studied. The acidity a †ects the catalystsÏ deactivation. The results of the initial activity clearly show a

## Abstract The perchlorate salt of the dicationic bipy–ruthenium complex __cis__‐[Ru(6,6′‐Cl~2~bipy)~2~(H~2~O)~2~]^2+^ effectively catalyzes addition of β‐diketones to secondary alcohols and styrenes to yield the α‐alkylated β‐diketones. In a catalytic addition reaction of acetylacetone to 1‐pheny

Because of their use as catalysts, the volume of papers published on the nature of the acid sites in zeolites is impressive. The number of acid sites is correctly estimated and their chemical nature is known. There are however numerous domains still largely unexplored, such as the structural descrip
