Syntheses and Properties of Donor/Acceptor Arylethynyl-Substituted 1,6-Methanoannulenes
Bryant-Friedrich, Amanda C.,Neidlein, Richard
, p. 1639 - 1647 (1997)
The stepwise palladium-catalyzed coupling of dibromo-1,6-methanoannulene derivatives to a phenylacetylene substituted by an electron-withdrawing group followed by coupling with a phenylacetylene possessing an electron-donating group allows the prepara
