Abstract

The synthesis and characterisation of two binaphthyl trisilanes is described. Reaction between 2,2'-dilithio1,1'- binaphthyl and 1,3-dichlorohexamethyltrisilane gave 3,3,4,4,5,5-hexamethyl-4,5-dihydro-3H-3,4,5- trisilacyclohepta[2,1-a; 4,3-a']binaphthalene (3). Compound 3 was characterised by H-1, C-13 and Si-29 NMR spectroscopy and a crystal structure analysis. Reaction between 2,2'-dilithio-1,1'-binaphthyl and 1,3-bis(trifluoromethanesulfonyloxy)-1,1,2,3,3-pentamethyltrisilane, generated in situ by treatment of 1,3-diphenyl-1,1,2,3,3-pentamethyltrisilane with trifluormethanesulfonic acid, gave 3,3,4,5,5-pentamethyl4,5- dihydro-3H-3,4,5-trisilacyclohepta[2,1-a; 4,3- a']binaphthalene (7). Analysis by H-1, C-13 and Si-29 NMR spectroscopy revealed that 7 had a very similar structure to 3. (C) 2008 Elsevier B. V. All rights reserved.
