Raney nickel / ˈ r eɪ n iː ˈ n ɪ k əl / also called spongy nickel is a fine-grained solid composed mostly of nickel derived from a nickel–aluminium alloy Several grades are known of which most are gray solids Some are pyrophoric most are used as air-stable slurries Raney nickel is used as a reagent and as a catalyst in organic chemistry It was developed in 1926 by American We report the conversion of amides to carboxylic acids using nonprecious metal catalysis The methodology strategically employs a nickel-catalyzed esterification using 2-(trimethylsilyl)ethanol followed by a fluoride-mediated deprotection in a single-pot operation This approach circumvents catalyst poisoning observed in attempts to directly hydrolyze amides using nickel catalysis The

The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service a division of the American Chemical Society to substances registered in the CAS registry database A substance identified primarily by an EC or list number may be linked with more than one CAS number or with CAS numbers that have been deleted

An iridium photocatalyst and visible light facilitate a room temperature nickel-catalyzed coupling of (hetero)aryl bromides with activated α-heterosubstituted or benzylic C(sp3)–H bonds Mechanistic investigations on this unprecedented transformation have uncovered the possibility of an unexpected mechanism hypothesized to involve a Ni–Br homolysis event from an excited-state nickel complex
