3-Iodoindoles, 5-bromo-3-iodoindoles and 5-bromo-3-iodoindazoles have been studied with respect to their reactivity and selectivity in palladium catalyzed Sonogashira and Suzuki cross-coupling reactions. As a result, sequential Sonogashira-Sonogashira, So

This paper describes a Sonogashira-type cross-coupling reaction of 3-iodoindazoles with various terminal alkynes as a general route to 3-alkynylindazoles. The coupling reaction is illustrated by the preparation of new indazolylpropiolic or propargylic derivatives. Scope and limitation of the method are outlined.
