Summary:
Tricarbonyl hydride derivatives of cyclopentadienyl-chromium, -molybdenum and -tungsten compounds covalently linked to a macroreticular polystyrene support are obtained by treatment of polystyrene-attached cyclopentadienyl anions with the respective metal hexacarbonyl and subsequent acidification. In contrast to the ease with which unsupported cyclopentadienyl-chromium and -molybdenum tricarbonyl hydrides lose H2 to form dinuclear carbonyl species, no H2 is released from their polymer-supported counterparts below about 180°C, and no dinuclear species are detectable after partial thermal decomposition at higher temperatures. The identity of the polymer-supported chromium species is confirmed by its conversion into nitrosyl derivatives.
