New stereoselective Csp2-Csp3 coupling: Catalytic iodomethylation of acetylene with methyl iodide into E-1-iodopropene

The catalytic addition of methyl iodide to acetylene yielding E-1-iodopropene has been discovered. The reaction competes with the formation of E,E-1,4-diiodobuta-1,3-diene. The key intermediate in these reactions is the methylvinyl derivative of PtIV

Platinum-catalyzed addition of iodomethane to acetylene

The reaction of iodomethane and acetylene in the presence of Pt II and NaI in acetone gives (E)-1-iodopropene. A possible mechanism involves the intermediate formation of a PtIV methyl vinyl derivative by the iodoplatination of acetylene with a reversibly formed a PtIV methyl complex and assumes the catalytic character of the process.
