title: CO and CO2 fixation by Se-Ru-CO hydride clusters.
abstract: The selective insertion of CO and CO2 into the C-O and O-H bonds of alcohols by the Se-Ru-CO hydride clusters [(μ-H)Ru4(CO)10Se2](-) (1) and [(μ3-H)Ru5(CO)14Se](-) (2) was demonstrated by a cooperative effect of the protonic hydride, the electron-rich Ru atom, and the electronegative Se atom as well as the symmetry of the clusters. These reactions generated the first examples of Se-containing ruthenium carboxylate and alkylcarbonate clusters [{(μ-H)Ru4(CO)10Se2}2{Ru2(CO)4(μ-η(1):η(1)-OOCR)}](3-) (R = Me, 3; Et, 4) and [{(μ-H)Ru4(CO)10Se2}2{Ru2(CO)4(μ-η(1):η(1)-OOCOR)}](3-) (R = Me, 5; Et, 6), respectively. These results disclosed herein provide a new avenue for the capture and storage of CO and CO2 and useful synthetic routes to novel RCOO(-)- and ROCOO(-)-bridged ruthenium selenide clusters.
