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 Aryl2SnH2. These exhibit high thermal stability and moderate oxygen tolerance.
