โฆ Synopsis
1.0-2.0 ppm due to the methylene and methine protons, and B singlet at 3.14 ppm due to the methoxy group. Heating of ethoxybenzene with HGeCI3 for 0.5 h at 110 to 1 3 0 ' C and subsequent methylation lead to t h e ethoxy derivatives corresponding to (3). I t is remarkable that the reaction of alkoxybenzenes and HGeCI3 docs not give rise to trichlorogermylbenzene, since refluxing of dialkyl ethers with HGeCI, produces alkyltrichlorogermanes in yields of 35-40
