Alk-2-enyl(trialkyl- and -triaryl)germanes are transmetallated by tin(IV) halides at −78 °C with 15 min being sufficient for the transmetallation to proceed effectively to completion. Alk-2-enyl(trialkyl)germanes are transmetallated by both tin(IV) chloride and tin(IV) bromide under these conditions, but the corresponding triphenylgermanes are only transmetallated using tin(IV) chloride. These observations
