Compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium, is researched, Molecular C18H28ClRu, CAS is 92390-26-6, about One-pot sequential four-component coupling via Cp*RuCl-catalyzed cyclotrimerization and Suzuki-Miyaura coupling. Author is Yamamoto, Yoshihiko; Ishii, Jun-ichi; Nishiyama, Hisao; Itoh, Kenji.
The catalytic intermol. cyclotrimerization of (alkynyl)boronate derivatives, propargyl alcs., and terminal alkynes was accomplished by means of the ruthenium catalysis and the temporary tethering approach with the C-B-O linkage to give rise to highly substituted (aryl)boronate derivatives with excellent selectivity. The resultant (aryl)boronate derivatives were further converted to highly substituted biaryls via the Suzuki-Miyaura coupling with various aryl iodides using Pd2(dba)3/PCy3 as a catalyst precursor in aqueous toluene. As a consequence, the four-component coupling approach to highly substituted biaryls was successfully established by combining these two operations into a sequential one-pot process.
