Abstract
Europium and ytterbium readily react with alkyl and aryl iodides in tetrahydrofuran. It is shown from the magnetic susceptibilities and a variety of analytical procedures that the solutions contain predominantly RMII| species. They undergo typical Grignard-type reactions. Samarium reacts less readily and the percentage of the bivalent state is considerably lower. Cerium also reacts under similar conditions to give moderate yields of organometallic species. Modifications of an n.m.r. method for determining magnetic susceptibilities are described.Keywords
