Reactions of trimethylsilyl-substituted alkynes with Cp2ZrCl2 and Et3Al in toluene at room temperature for 18 hours give functionalized products of homo-coupling in good yield. Trimethylsilyl-substituted alpha,omega-diynes react to form (1Z,2Z)-1,2-bis(iodo(trimethylsilyl)methylene)cycloalkanes after iodinolysis.
The reaction of trimethylsilyl-substituted alkynes with 0.5 equivalents of Cp2ZrCl2 and 1 equivalent of Et3Al in toluene at room temperature for 18 hours gives, after hydrolysis/deuterolysis or iodination, functionalized products of the homo-coupling of silyl-substituted alkynes in good yield. Trimethylsilyl-substituted alpha,omega-diynes react with the Cp2ZrCl2 - Et3Al reagent system to give (1Z,2Z)-1,2-bis(iodo(trimethylsilyl)methylene)cycloalkanes after iodinolysis.
