Selective Preparation of Sterically Encumbered Diaryltin Dihalides from Grignard Reagents via Salt Metathesis and Halide Exchange

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.

Nickel-triad complexes of a side-on coordinating distannene

NHC adducts of the stannylene Trip2Sn (Trip=2,4,6-triisopropylphenyl) were reacted with zero-valent Ni, Pd, and Pt precursor complexes to cleanly yield the respective metal complexes featuring a three-membered ring moiety Sn-Sn-M along with carbene transfer onto the metal and complete substitution of the starting ligands. Thus the easily accessible NHC adducts to stannylenes are shown to be valuable precursors for transition-metal complexes with an unexpected Sn-Sn bond. The complexes have been studied by X-ray diffraction and NMR spectroscopy as well as DFT calculations. The compounds featuring the structural motif of a distannametallacycle comprised of a [(NHC)2M0] fragment and Sn2Trip4 represent rare higher congeners of the well-known olefin complexes. DFT calculations indicate the presence of a π-type Sn-Sn interaction in these first examples for acyclic distannenes symmetrically coordinating to a zero-valent transition metal.

Attempted synthesis of a transition-metal stannaphosphene complex

Fluoro-, chloro- and bromostannylphosphines (8-10) complexed on phosphorus by tungsten pentacarbonyl have been synthesized by reaction between lithium mesityl(tungsten pentacarbonyl)phosphide 4 and the corresponding dihalo(diisityl)tin (isityl: 2,4,6-triisopropylphenyl). Reaction of 8 with tert-butyllithium afforded the stable lithium fluorostannylphosphide 11. Addition of Me3SiCl or MgBr2 to 11 gave the corresponding chloro- and bromoderivatives 14 and 15. Similar compounds 16 and 17 were obtained from 9 and 10 and DBU. 11, 14, 15, 16 and 17 present a large 1JSnP coupling constant (2099.0 to 2151.4 Hz) indicating a partial Sn-P double bond.
