Organometallic synthesis via "surface-mediated" reactions: high-yield route to HOs3(CO)10(OH)

The silica-anchored hydrido cluster HOs3-(CO)10(OSi←) is easily prepared from physisorbed Os3(CO)12. Chemical displacement from the surface with HF leads to the isolation of pure HOs3(CO)10(OH). This approach is far simpler and gives much higher yields than the conventional syntheses in solution.
