Abstract/Summary

Metallation of ArBr (Ar = 2,6-diethylphenyl) with Li powder in diethyl ether, followed by addition of stannous chloride at low temperature does not give the expected oligomeric diarylstannane but an essentially quantitative yield of the novel tetrastannabutane [{SnAr2}3SnArBr]. Some reactions of the new species are reported.
