Reactions of Tin-Naphthyl Bond with Halogens and Pseudohalogens

Bhattacharya, S. N.,Husain, Ishrat

, p. 1119 - 1121 (2007/10/02)

Reactivity of Sn-phenyl or Sn-naphthyl bond in tetraorganotins, PhnSnNp4-n (Ph = phenyl, Np = α-naphthyl; n = 2,3) towards halogens (Br2 and I2), interhalogens (IBr and ICl), interpseudohalogens (BrCN and ICN) and pseudohalogen (SCN)2 has been studied.It is found that the Sn-Np bond is preferentially cleaved yielding in most cases phenyltin derivatives along with the corresponding α-naphthyl halides.
