- Abstract
The Sonogashira coupling of 1,8-bis(dimethylamino)-2-iodonaphthalene with 2-nitro-, 4-nitro-, 4-(trifluoromethyl)-, and 4-methoxyphenylacetylenes was used to obtain new 2-(arylethynyl)-1,8-bis(dimethylamino)naphthalenes. Three of the four alkynes, except for the
o -nitrophenyl derivative, were isomerized in the presence of palladium and porcelain catalysis to the corresponding 2-aryl-9-(dimethylamino)-1,3-dimethyl-1H -benzo[g ]indoles. [ABSTRACT FROM AUTHOR]
