The deposition of K2[Ru4(CO)13], K2[Os3(CO)11], K2[Fe2(CO)8], and K[Re(CO)5] onto graphite-like carbon “Sibunit” followed by the thermal decomposition of the supported carbonylmetallate in a flow of dihydrogen or argon affords systems capable of activating C-H bonds of methane, ethylene, and acetylene and of introducing them into hydrogen-deuterium exchange reactions. In the case of ethylene and acetylene
K2[Ru4(CO)13]、K2[Os3(CO)11]、K2[Fe2(CO)8]和K[Re(CO)5]沉积在类石墨碳“Sibunit”上,然后负载的羰基
