Consecutive one-pot sonogashira-glaser coupling sequence- Direct preparation of symmetrical diynes by sequential Pd/Cu catalysis
Sonogashira coupling and the catalytic Glaser coupling are both catalyzed by the Pd-Cu complex couple and can be concatenated to a consecutive sequentially Pd/Cu-catalyzed process in a one-pot fashion, and air oxygen serves as the only oxidant in the second step. In a pseudo-four-component synthesis, a broad variety of symmetrically substituted 1,4-bis(hetero)aryl-1,3-butadiynes are obtained in good to excellent yields. Interestingly, the presence of iodide ions has been found to be advantageous over other halides to trigger the Pd/Cu-catalyzed Glaser step, and Pd and Cu species, as well as triethylamine as a base, are prerequisite for both couplings, which proceed with higher efficiency if performed in a one-pot sequence. Two catalytic alkyne coupling reactions were combined in a consecutive sequentially Pd/Cu-catalyzed process to furnish a novel pseudo-four-component synthesis of a variety of symmetrically substituted 1,4-bis(hetero)aryl-1,3-butadiynes in goodyields. Pd and Cu species and triethylamine (base) are essential for the couplings, which proceed with higher efficiency if performed in a one-pot sequence. Copyright
