Mechanochemically Driven Transformations in Organotin Chemistry: Stereochemical Rearrangement, Redox Behavior, and Dispersion-Stabilized Complexes

Ball milling a mixture of the bulky allyl K­[A′] {[A′] = [1,3-(SiMe3)2C3H3]−} and SnCl2 in a 2:1 ratio for 5 min leads to the tris­(allyl) stannate [SnA′3K]∞, which forms a coordination polymer in the solid state. Longer grinding of the 2:1 mixture (15 min), or the use of a 3:1 ratio of reagents, in...

Zusammenfassung:Ball milling a mixture of the bulky allyl K­[A′] {[A′] = [1,3-(SiMe3)2C3H3]−} and SnCl2 in a 2:1 ratio for 5 min leads to the tris­(allyl) stannate [SnA′3K]∞, which forms a coordination polymer in the solid state. Longer grinding of the 2:1 mixture (15 min), or the use of a 3:1 ratio of reagents, initiates a disproportionation reaction and the chiral tetra­(allyl)­tin species [SnA′4] is produced. A small amount of a diastereomeric [SnA′4] complex with meso symmetry can also be isolated with extended grinding. These products have been structurally authenticated with single-crystal X-ray crystallography. The tetra­(allyl) species [SnA′4] are sterically crowded and decompose relatively quickly (
