N. Rot et al., Synthesis of 1,3,5-tri- and 1,2,4,5-tetrasubstituted tin and mercury derivatives of benzene. Crystal structure of 1,3,5-tris(chloromercurio)benzene, J ORGMET CH, 594, 2000, pp. 369-379
The reaction of 1,3,5-tribromo- or 1,2,4,5-tetrabromobenzene with trimethyl
stannyl sodium in tetraglyme gave the corresponding polystannylated benzene
derivatives 2 and 4, respectively, in high yield. They were converted with
mercuric chloride to the corresponding tris- and tetrakis(chloromercurio)b
enzenes 5 and 6, respectively. The structure of 5 was confirmed by X-ray cr
ystallography. Some spectral properties of the new compounds are discussed.
The (partial) conversion of 2 to 1,3,5-trilithiobenzene (8) was also inves
tigated. (C) 2000 Elsevier Science S.A. All rights reserved.
