Trans Additions of Silanes to 1-Alkynes Catalyzed by Ruthenium Complexes: Role of in Situ Formed Polynuclear Aggregates
摘要:
(Z)-Alkenyl ligands are formed by insertion of 1-alkynes into bridging hydrides. The unusual stereoselectivity of this elementary step may account for the selectivity toward (Z)-alkenylsilanes frequently observed in 1-alkyne hydrosilylations catalyzed by basic late-transition-metal complexes.
