The supplementary information provides detailed experimental procedures and results for a series of olefin cross metathesis reactions. The reactions were conducted using various olefins and catalysts in dichloromethane (CH₂Cl₂) under nitrogen atmosphere at room temperature for 12 hours. The products were purified directly on silica gel columns and characterized by nuclear magnetic resonance (NMR) spectroscopy, high-resolution mass spectrometry (HRMS), and thin-layer chromatography (TLC). The yields and stereochemistry of the products were determined, and the results are consistent with previously reported compounds. The reactions successfully produced a range of products, including cis and trans isomers, with specific E/Z ratios determined by ¹H-NMR analysis. The experimental procedures and characterization details are provided for each compound, highlighting the versatility and selectivity of the olefin cross metathesis reactions.The supplementary information provides detailed experimental procedures and results for a series of olefin cross metathesis reactions.
