Abstract

Synthesis of a variety of anti-2,7-disubstituted norbornadienes was achieved by palladium- and iron-catalyzed cross-coupling­ reactions of the anti-tert-butoxynorbornadien-2-yl triflate. While the palladium-catalyzed coupling reactions could only generate coupling products with aryl and alkynyl groups, the iron-catalyzed coupling reactions have a much broader scope and provide efficient synthesis of anti-2,7-disubstituted norbornadienes with attached primary, secondary and tertiary alkyl groups, cycloalkyl groups with various ring sizes, as well as vinyl, aryl and alkynyl groups.
