Understanding and Controlling Reactivity of Unsaturated Oxygenates and Polyols on Metal Catalysts

“…The selective hydrogenation of unsaturated aldehydes such as acrolein, crotonaldehyde, and prenal to unsaturated alcohols has been a major focus of catalysis research for decades, and the chemistry has been the subject of extensive reviews. − We will therefore focus primarily on recent surface-level investigations of this chemistry. See Scheme for a summary of the basic reaction paths.…”

Polar Intermetallic Compounds as Catalysts for Hydrogenation Reactions: Synthesis, Structures, Bonding, and Catalytic Properties of Ca1−xSrxNi4Sn2 (x=0.0, 0.5, 1.0) and Catalytic Properties of Ni3Sn and Ni3Sn2

“…The Ni 3 Sn and Ni 3 Sn 2 phases reached conversions of 12.7 and 37.5 %, the latter is comparable to supported metal catalysts. [42] High selectivities to the unsaturated alcohols geraniol and nerol of 50 and 71 % were reached. Samples of CaNi 4 Sn 2 , SrNi 4 Sn 2 , Ca 0.5 Sr 0.5 Ni 4 Sn 2 , Ni 3 Sn, Ni 3 Sn 2 , and MgCo 6 Ge 6 yielded comparable geraniol/nerol product ratios of % 2.…”
