An organocadmium compound is an organometallic compound containing a carbon to cadmium chemical bond. Organocadmium chemistry describes physical properties, synthesis, reactions and use of these compounds.〔''Synthetic Methods of Organometallic and Inorganic Chemistry Vol 5, Copper, Silver, Gold, Zinc, Cadmium, and Mercury'' W.A. Herrmann Ed. ISBN 3-13-103061-5〕 Cadmium shares group 12 with zinc and mercury and their corresponding chemistries have much in common. Dimethylcadmium is a linear molecule with C-Cd bond lengths of 211.2 pm. All organocadmium compounds are sensitive to air, light and moisture. == Synthesis== The first organocadmium compounds, dimethylcadmium, CH3-Cd-CH3, and diethylcadmium, CH3CH2-Cd-CH2CH3, were prepared in 1917 by Erich Krause. In general, they are prepared by transmetalation or by an exchange reaction between an organometallic reagent and a cadmium salt. One procedure for the synthesis of diethylcadmium is by the reaction of cadmium bromide with two equivalents of the Grignard reagent ethylmagnesium bromide in diethyl ether. A byproduct is magnesium bromide. Diethylcadmium is a colorless oil with melting point −21 °C. Diphenylcadmium can be prepared by the reaction of phenyllithium with cadmium bromide. Diphenylcadmium is a solid with a melting point of 174 °C. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Organocadmium compound」の詳細全文を読む スポンサード リンク
