Platinum has attracted significant attention in organometallic chemistry and plays a crucial role in various organic molecular activations, such as C-H activation and alkene activation, contributing to the understanding of general principles of platinum chemistry.
Over the past few decades, platinum has attracted remarkable attention and played an important role in promoting construction of C-X (X = C, O, N, B, etc.) bonds in organometallic chemistry. However, understanding the general principle of Pt chemistry is still an urgent task both experimentally and theoretically. Differing from other metals in the same group, such as Ni and Pd, Pt-mediated C-H activation processes mainly involve oxidative addition, sigma-complex assisted metathesis, outersphere electrophilic deprotonation, and even carbene Pt complex insertion rather than concerted metalation-deprotonation. In some other catalysis, Pt possesses a strong Lewis acid property to activate a wide range of unsaturated substrates. In this review, the mechanistic principles and recent advancements of various types of Pt-mediated organic molecular activations, including C-H activation, alkyne activation, alkene activation, and allene activation, are systematically summarized from a theoretical viewpoint. These activations generally result in Pt-C bond formation, which can be further transformed for construction of new C-C and C-heteroatom bonds. (C) 2021 Elsevier B.V. All rights reserved.
