Synthesis of 7,7,14,14-tetrachlorodinaphtho[1,8bc:1′,8′-fg][1,5]distannocine. Molecular structure of the di-water tetra-THF adduct

Abstract

The salt metathesis reaction of 1,8-dilithionaphthalene with tributyltin chloride provided 1,8-bis(tributyltin)naphthalene (1) in 41% yield. The transmetallation of 1 with tin tetrachloride gave rise to the formation of 7,7,14,14-tetrachlorodinaphtho[1,8bc:1′,8′-fg][1,5]distannocine (2) in 75% yield. The molecular structure of 2·2 H2O·4 THF was established by single crystal X-ray crystallography.
