A One‐Pot Strategy for the Synthesis of β‐Substituted Rhoda‐ and Irida‐Carbolong Complexes

Abstract

Starting from an organic multiyne, three steps are normally needed for the preparation of non--phosphonium functionalized rhodaand irida-carbolong complexes. Herein, a one-pot strategy, by mixing a multiyne, a nucleophile, and RhCl(CO)(PPh3)2/AgBF4 or [Ir(CH3CN)(CO)(PPh3)2]BF4, was developed to achieve a series of -functionalized rhoda-and irida-carbolong complexes. The -substituents in these complexes can be various C-, N-and O-centered groups, dependent on the nucleophiles used. This strategy provides a new convenient route to construct carbolong complexes, which is important for the further development of carbolong chemistry.
