Abstract: Abstract Thermal treatment of Ru3(CO)12 with 3-(6-ethyl-2-pyridyl)indene in refluxing toluene gave a triruthenium carbonyl complex {μ2-η5:η1-(C2H5C5H4N)(C9H5)}Ru3(CO)9 (1) via regioselective C(sp2)–H activation. While reaction of 2-methyl-3-(6-ethyl-2-pyridyl)indene with Ru3(CO)12 generated a dinuclear ruthenium complex {(C2H5C5H4N)(μ2-η5,η1-C9H5CH2)}Ru2(CO)5 (2) via… read more here.

Abstract: Alkynes occupy a prominent role as a coupling partner in the transition metal-catalysed directed C-H activation reactions. Due to low steric requirements and linear geometry, alkynes can effectively coordinate with metal d-orbitals. This makes alkynes… read more here.
