Photocatalytic Dehydrogenation of Primary Alcohols: Selectivity Goes against Adsorptivity

PNP pincer osmium polyhydrides for catalytic dehydrogenation of primary alcohols.

This paper reports the synthesis, structure, and properties of a series of PNP pincer complexes of osmium OsH(3)Cl[HN(C(2)H(4)P(i)Pr(2))(2)] (1), OsH(3)[N(C(2)H(4)P(i)Pr(2))(2)] (2), OsH(4)[HN(C(2)H(4)P(i)Pr(2))(2)] (3), and OsH(2)(PMe(3))[HN(C(2)H(4)P(i)Pr(2))(2)] (4). The tetrahydride 3 operates as an efficient catalyst at 0.1 mol% loading for the reactions of amination and dehydrogenative co...

Reversible catalytic dehydrogenation of alcohols for energy storage.

Reversibility of a dehydrogenation/hydrogenation catalytic reaction has been an elusive target for homogeneous catalysis. In this report, reversible acceptorless dehydrogenation of secondary alcohols and diols on iron pincer complexes and reversible oxidative dehydrogenation of primary alcohols/reduction of aldehydes with separate transfer of protons and electrons on iridium complexes are shown...

Titanium carbenoid-mediated cyclopropanation of allylic alcohols: selectivity and mechanism.

A new method for the chemo- and stereoselective conversion of allylic alcohols into the corresponding cyclopropane derivatives has been developed. The cyclopropanation reaction was carried out with an unprecedented titanium carbenoid generated in situ from Nugent's reagent, manganese and methylene diiodide. The reaction involving the participation of an allylic hydroxyl group, proceeded with co...

Dehydrogenation of Propane to Propylene Over Pt-Sn/Al2O3 Catalysts: The influence of operating conditions on product selectivity

Gold nanoparticles on hydrotalcites as efficient catalysts for oxidant-free dehydrogenation of alcohols.

Hydrotalcite-supported gold nanoparticles with sizes of less than 5 nm are highly efficient and reusable catalysts for the oxidant-free dehydrogenation of alcohols to carbonyl compounds and hydrogen.
