R2(HMe2Si)CCl (R = SiMe3) reacted with ICl to give the iodide R2(ClMe2Si)CI, which with MeOH gave R2(MeOMe2Si)CI. This reacted with Mg in Et2O to give MgI2(OEt2)2 (which was isolated and structurally characterised) and the chelated dialkylmagnesium Me)}2, apparently following initial formation of the Grignard reagent MegI. The latter compound was isolated from the products of the reaction between the iodide
