Manganese(II) chloride

Manganese(II) chloride is the dichloride salt of manganese, MnCl2. This inorganic chemical exists in the anhydrous form, as well as the dihydrate (MnCl2·2H2O) and tetrahydrate (MnCl2·4H2O), with the tetrahydrate being the most common form. Like many Mn(II) species, these salts are pink, with the paleness of the color being characteristic of transition metal complexes with high spin d5 configurations. It is a paramagnetic salt.

Dysprosium(III) chloride

Dysprosium(III) chloride (DyCl3), also known as dysprosium trichloride, is a compound of dysprosium and chlorine. It is a white to yellow solid which rapidly absorbs water on exposure to moist air to form a hexahydrate, DyCl3·6H2O. Simple rapid heating

Chromium(III) chloride

Chromium(III) chloride (also called chromic chloride) describes any of several chemical compounds with the formula CrCl3 · x H2O, where x can be 0, 5, and 6. The anhydrous compound with the formula CrCl3 is a violet solid. The most common form of the

P-Toluic acid

p-Toluic acid (4-methylbenzoic acid) is a substituted benzoic acid with the formula CH3C6H4CO2H. It is a white solid that is poorly soluble in water but soluble in acetone. A laboratory route to p-toluic acid involves oxidation of p-cymene with nitric

Samarium(II) iodide

Samarium(II) iodide is an inorganic compound with the formula SmI2. When employed as a solution for organic synthesis, it is known as Kagan's reagent. SmI2 is a green solid and solutions are green as well. It is a strong one-electron reducing agent that

Phosphorus triiodide

Phosphorus triiodide (PI3) is an inorganic compound with the formula PI3. A red solid, it is a common misconception that PI3 is too unstable to be stored; it is, in fact, commercially available. It is widely used in organic chemistry for converting

Phosphorus trifluoride

Phosphorus trifluoride (formula PF3), is a colorless and odorless gas. It is highly toxic and reacts slowly with water. Its main use is as a ligand in metal complexes. As a ligand, it parallels carbon monoxide in metal carbonyls, and indeed its toxicity

Alkylammonium

In organic chemistry, alkylammonium refers to cations of the formula [R4−nNHn]+, where R = alkyl and 1≤ n ≤ 4. The cations with four alkyl substituents, i.e., [R4N]+, are further classified as quaternary ammonium cations and are discussed more
