Exchangereactions of spirocyclic stannoles with boron, tin and phosphorus halides lead to stannoles 4, 5 and 6, 7, in which the tin atoms bear two chloro or two bromo ligands. The same stannoles 4 and 5 were prepared by 1,1-ethylboration of bis(trimethylsilylethynyl)tin dichloride (8) or -dibromide (9), prepared in situ from tetrakis(trimethylsilylethynyl)tin and tin tetrachlodide or -tetrabromide
