Webb12 apr. 2024 · As shown in Scheme 1, the Chalk–Harrod mechanism is divided into three steps: (1) Si-H oxidative addition to Pt, (2) alkene insertion into the Pt-H bond, and (3) Si-C reductive elimination. In the modified Chalk–Harrod mechanism, the second step is replaced by alkene insertion into the Pt-Si bond, followed by the C-H reductive elimination.

WebbOzone reacts with an alkene via a cycloaddition reaction to form an unstable 5-membered ring called a molozonide.
