Diiodomethane or methylene iodide, commonly abbreviated "MI", is an organoiodine compound. Diiodomethane is a very dense colorless liquid; however, it...

Trimethylsulfoxonium iodide is a sulfoxonium salt. It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride. The latter compound...

A methylene group is any part of a molecule that consists of two hydrogen atoms bound to a carbon atom, which is connected to the remainder of the molecule...

millilitre of methylene iodide weighs 3.325 g. Few organoiodine compounds are important industrially, at least in terms of large scale production. Iodide-containing...

(1764–1838), a student of Lavoisier, first obtained phosphine in 1783 by heating white phosphorus in an aqueous solution of potash (potassium carbonate). Perhaps...

that reacts by the SN2 pathway: CH3OH + H+ → [CH3OH2]+ Similarly, methyl iodide and methyl triflate are viewed as the equivalent of the methyl cation because...
