The compound resorcinol, hydrogenated with Raney nickel in presence of aqueous sodium hydroxide forms an enolate which is alkylated with methyl iodide to 2-methyl-1, 3-cyclohexandione:

For laboratory syntheses, Raney nickel ( an alloy of nickel and aluminium ) is often employed.

Examples are nickel, such as Raney nickel for hydrogenation, and vanadium ( V ) oxide for oxidation of sulfur dioxide into sulfur trioxide.

* Used hydrogenation catalysts such as Raney nickel ( especially hazardous because of the adsorbed hydrogen )

Raney nickel is useful for stoichiometric reactions in organic synthesis whereas molybdenum-based catalysts are used to " sweeten " petroleum fractions, in the process called hydrodesulfurization.

Finally, the nitro group is reduced by hydrogenation over Raney nickel catalyst.

2-Methylimidazole ( 1 ) may be prepared via the Debus-Radziszewski imidazole synthesis, or from ethylenediamine and acetic acid, followed by treatment with lime, then Raney nickel.

Symmetric secondary amines can be prepared using Raney nickel ( 2RNH < sub > 2 </ sub > → R < sub > 2 </ sub > NH + NH < sub > 3 </ sub >).

Thioketals undergo hydrogenolysis using Raney nickel in the Mozingo reduction.

The nitro of 16 is then reacted with methanol, Raney nickel, and hydrogen to give diamine 17 in 82 % yield.

The synthesis of buspirone starts with the N-alkylation of 1 -( 2-pyrimidyl ) piperazine with 4-chlorobutyronitrile followed by hydrogenation of the nitrile over Raney nickel catalyst.

* Raney nickel

# The nitro group is reduced with hydrogen gas over Raney nickel catalyst.

Treatment of this derivative with Raney nickel remove the thioether group.

Dry activated Raney nickel.

Raney nickel is used as a reagent and as a catalyst in organic chemistry.

Since Raney is a registered trademark of W. R. Grace and Company, only those products by its Grace Division division are properly called " Raney nickel ".

The more generic terms " skeletal catalyst " or " sponge-metal catalyst " may be used to refer to catalysts with physical and chemical properties similar to those of Raney nickel.

Raney nickel is pyrophoric and must be handled with care.

The surface area of Raney nickel ( and related catalysts in general ) tends to decrease with increasing leaching temperature.

The thioether is removed in step 2 by Raney Nickel / hydrogen reduction

This is accentuated by the artwork of Tom Raney, the inks of Randy Elliot and the changing palette of Laura DePuy and Wildstorm FX.

However, since the Grace company itself does not use any generic names for the catalysts it is supplying, " Raney " may become generic under US trademark law.

For this reason, commercial Raney nickel is available in both " active " and " inactive " forms.

Macroscopically, Raney nickel is a finely divided gray powder.

Raney nickel is notable for being thermally and structurally stable, as well has having a large BET ( Brunauer-Emmett-Teller ) surface area.

A high catalytic activity, coupled with the fact that hydrogen is absorbed within the pores of the catalyst during activation, makes Raney nickel a useful catalyst for many hydrogenation reactions.

Additionally, the solubility of Raney nickel is negligible in most common laboratory solvents, with the exception of mineral acids such as hydrochloric acid, and its relatively high density ( about 6. 5 g / cm < sup > 3 </ sup >) also facilitates its separation from a liquid phase after a reaction is completed.

Raney nickel is used in a large number of industrial processes and in organic synthesis because of its stability and high catalytic activity at room temperature.

A practical example of the use of Raney nickel in industry is shown in the following reaction, where benzene is reduced to cyclohexane.

Reduction of the benzene ring is very hard to achieve through other chemical means, but can be effected by using Raney nickel.

Benzene is routinely reduced to cyclohexane using Raney nickel for the production of nylon.

Raney resigned from the legislature the next year in order to accept an appointment to the Supreme Court of Ontario and 72 year old John Giles Lethbridge was chosen as the new leader of the Progressives.

It was support from unexpected places, such as M. Llewellyn Raney of the University of Chicago libraries, which alleviated the ALA letter writing campaign against MacLeish ’ s nomination.

Raney pointed out to the detractors that, “ MacLeish was a lawyer like Putnam ... he was equally at home in the arts as one of the four leading American poets now alive ... and while it was true that he had not attended a professional school of library science, neither had thirty-four of thirty-seven persons presently occupying executive positions at the Library of Congress .” The main Republican arguments against MacLeish ’ s nomination from within Congress was: that he was a poet and was a “ fellow traveler ” or sympathetic to communist causes.

Raney, with support from his listeners, persuaded the station's management to retain the rock format.

After the defeat of the United Farmers of Ontario in the previous election, the farmers organization decided to withdraw from electoral politics and most UFO MPPs redesignated themselves as Progressives with former UFO Attorney-General William Edgar Raney becoming party leader.

The aircraft crashed approximately 100 yards from a beach where Mr. Raney was attempting to make an emergency landing before striking the coconut trees just short of the beach.

Born on a farm near Aultsville, Ontario, ( interestingly, another notable Ontario politician, Sir James Whitney, was born on the farm adjacent to it ) to Herman and Mary Raney, William E. Raney descended from Huguenot and United Empire Loyalist stock.
