  Spiro[2,5-dibenzo-1,4-disilacyclohexa-2,5-diene-1,7′-2′,5′- dibenzo-1′,4′,7′-trisilanorbornadiene]: Unusual Dimerization of Silyl-Substituted 9,10-Disila(Dewar Anthracene)

  摘要：

  The reduction of 9,10-dibromo-9,10-dihydro-9,10-disilaanthracene (3) with 2.2 equiv. of KC8 in THF afforded the unexpected spiro[2,5-dibenzo-1,4-disilacyclohexa-2,5-diene-1,7'-2',5'-dibenzo-1',4',7'-trisilanorbornadiene] (4) through the dimerization of the transient 9,10-disila-9,10-Dewar anthracene (5). The formation of 5 was demonstrated by low-temperature NMR spectroscopy.
