Polymethyl derivatives of digermane
Abstract
When the products from the reaction of digermane or methyldigermane with iodine at temperatures > – 63° were treated with MeMgl, the new compounds 1,1- and 1,2-dimethyldigermane, and 1,1,2-trimethyldigermane were prepared. The 1H n.m.r. and vibrational spectra are reported and the course of the reaction discussed. Small amounts of three further new products were tentatively identified as the two tetra- and penta-methyldigermanes.
