An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.65×53mm Mauser, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is ...
In this complex, the diene is easily displaced, which makes it a favored precursor to catalysts. In the industrially important Wacker process, ethylene is converted to acetaldehyde via nucleophilic attack of hydroxide on a Pd(II)-ethylene intermediate followed by formation of a vinyl alcohol complex. Fullerene ligands also bind with palladium(II).
The .280 British was an experimental rimless bottlenecked intermediate rifle cartridge.It was later designated 7 mm MK1Z, and has also been known as .280/30, .280 Enfield, 7 mm FN Short and 7×43mm.
The intermediate then undergoes dehydration, followed by migration of boronate-alkyl group to furnish the final carboxylic acid product. A wide range of aryl boronic acids is tolerated, while the usage of vinyl boronic acids is not reported.
A key intermediate is cobalt tetracarbonyl hydride (HCo(CO) 4). Processes involving cobalt are practiced commercially mainly for the production of C7-C14 alcohols used for the production of surfactants. [10] [11] Many hydroformylations have switched from cobalt-based processes to rhodium-based processes, despite the great expense of that metal.
Vinyl cations were first proposed in 1944 as a reactive intermediate for the acid-catalyzed hydrolysis of alkoxyacetylenes to give alkyl acetate. [5] In the first step of their facile hydration reaction, which was the rate limiting step, a vinyl cation reactive intermediate was proposed; the positive charge was believed to formally lie on a ...

The reaction is accelerated in the presence of dichloroacetic acid, which forms the lead(IV) dichloroacetate as an intermediate. Other organolead compounds are the halides of the type R n PbX (4-n), sulfinates (R n Pb(OSOR) (4−n)) and hydroxides (R n Pb(OH) (4−n)). Typical reactions are: [5] R 4 Pb + HCl → R 3 PbCl + RH R 4 Pb + SO 2 → ...
