Hydrocarbon C—H Bond Activation with Tp'Pt Complexes

Mechanistic Aspects of C−H Activation by Pt Complexes

“…This contrasts the many reports of C−H elimination from mixed hydridoalkyl and aryl complexes, as will now be discussed. Parts of this chemistry have been recently reviewed 73 …”

Copper-Mediated Multiple C–H Functionalization of Aromatic N-Heterocycles: Bromoamination of Indoles and Pyrroles

“…This new methodology of installing functional groups on the aryl skeleton is greener, as it obviates the need for prefunctionalized substrates and, hence, the resulting waste during synthesis, yet presently suffers from several limitations. The more often encountered ones are the need for a directing group, which dictates the regiochemistry of the functionalization, and the use of catalysts derived from expensive second- or third-row late transition metals such as Pd, Pt, Ru, Rh, Ir, and Au . While new reports of C–H functionalization using late metals continue to emerge, growing concerns regarding their toxicity and cost-effectiveness have prompted interest in the use of cheap, benign, and readily available first-row metals such as Fe and Cu .…”
