Organozinc reagents are among the most commonly used organometallicreagents in modern synthetic chemistry, and multifunctionalized organozinc reagents can be synthesized from structurally simple, readily available ones by means of alkyne carbozincation. However, this method suffers from poor tolerance for terminal alkynes, and transformation of the newly introduced organic groups is difficult, which

substrates in the Suzuki and Sonogashira/Castro-Stevens palladium catalyzed chemistry is exemplifed. These derivatized phenanthrolines are seen as key buildingblocks for the design and construction of topologically complexpolynuclearmetal coordination complexes.
