Dimethylcadmium is theorganocadmium compound with the formulaCd(CH3)2. It is a colorless, highly toxic liquid that fumes in air. It is a linear molecule with C-Cd bond lengths of 213 pm.[1] The compound finds limited use as a reagent inorganic synthesis and inmetalorganic chemical vapor deposition (MOCVD). It has also been used in the synthesis ofcadmium selenide nanoparticles, although efforts have been made to replace it in this capacity due to its toxicity.[2]
Dimethylcadmium is prepared by treating cadmium dihalides with methylGrignard reagents ormethyllithium.[3]
The same method was used in the first preparation of this compound.[4]
Dimethylcadmium is a weakLewis acid, forming a labile adduct withdiethyl ether. A yellow, air-sensitive adduct is formed with2,2'-bipyridine.[3]
