The syntheses of novel well-defined star-shaped carbazole-functionalized triazatruxenes, which consist of six carbazole arms linked with a central triazatruxene core consisting of three carbazoles with one phenyl, are presented. Both 9-hexylcarbazole and 9-phenylcarbazole as arms gave high yields. Their chemical formulas were confirmed by means of 1 H NMR, MALDI-TOF mass spectroscopy, and...
A new, high yield, convenient synthesis of 7-(tert-butoxycarbonyl)-7-azabicyclo[2.2.1]hept-2-ene which involved the addition of tributyltin hydride to 7-(tert-butoxycarbonyl)-2-p-toluenesulfonyl-7-azabicyclo[2.2.1]-2-ene followed by elimination of the tributyltin and p-tolylsulfonyl groups using tetrabutylammonium fluoride was developed.
