A general route for the selective preparation of diaryltin dichlorides, dibromides, and diiodides from readily accessible but sterically demanding, 2,6‐disubstituted or 2,4,6‐trisubstituted aryl Grignard reagents ArylMgBr and tin tetrachloride was developed. During work‐up, the initially obtained mixture of halides is converted into a single species. The thus obtained diaryltin dichlorides were reacted to yield the dihydrides Aryl 2 SnH 2 . These exhibit high thermal stability and moderate oxygen tolerance.
