Hydrogenation on granular palladium-containing catalysts: I. Hydrogenation of tertiary acetylene alcohols

Commercial granular palladium catalyst (0.5% of Pd on γ-Al 2O3) was modified by treating with zinc acetate (type 1) or successively with zinc acetate and ammonia (type 2). The treatment significantly increased the hydrogenation selectivity for a triple bond into a double bond: to 85.3-93.1% with the type 1 catalyst and to 96.3-97.8% with the type 2 catalyst. A construction of an autoclave with a fixed bed of the granular catalyst is described.

ORGANIC SYNTHESES WITH SULFONES (PART XXVIII) ;SYNTHESIS OF TERPENOID COMPOUNDS BY WAY OF MICHAEL ADDITION REACTIONS TO CONJUGATED DIENYL SULFONES.

Michael additions of ethanol and ketones to allyl-dienyl sulfones yielded di-allylic sulfones which were transformed into isoprenoid compounds by either Ramberg-Baecklund reaction or thermolysis.

HYDROGENATION OF ACETYLENIC COMPOUNDS IN THE PRESENCE OF A COMPLEX CATALYST BASED ON NICKEL STEARATE AND TRIETHYLALUMINUM

Hydrogenation in the presence of a catalytic system based on nickel stearate and triethylaluminum was investigated for the following acetylenic compounds: Phenylacetylene; 1-hexyne; dimethylethynylcarbinol; dimethylvinylethynylcarbinol; 3,7,11,15-tetramethyl-1-hexadecyn-3-ol.The hydrogenation rate of the triple bond decreases in the order 1-hexyne > phenylacetylene > dimethylethynylcarbinol.The selectivity of the hydrogenation of the alcohols increases with increase in the molar ratio of the components of the Al(C2H5)3/Ni(C17H35COO)2.
