Abstract
Abstract The synthesis and characterisation of two binaphthyl trisilanes is described. Reaction between 2,2′-dilithio-1,1′-binaphthyl and 1,3-dichlorohexamethyltrisilane gave 3,3,4,4,5,5-hexamethyl-4,5-dihydro-3 H -3,4,5-trisilacyclohepta[2,1-a;4,3-a′]binaphthalene ( 3 ). Compound 3 was characterised by 1 H, 13 C and 29 Si 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-pentamethyl-4,5-dihydro-3 H -3,4,5-trisilacyclohepta[2,1-a;4,3-a′]binaphthalene ( 7 ). Analysis by 1 H, 13 C and 29 Si NMR spectroscopy revealed that 7 had a very similar structure to 3 .
