Abstract
Dienes have a wide importance throughout synthetic chemistry. While there are many methods for their preparation, this paper provides an excellent protocol for the stereoselective synthesis of Si/Sn 2,3-bis-metallo-dienes. The first step involves hydromagnesiation of alkynyl silanes via titanium catalysis. This vinyl magnesium bromide is then coupled with a vinyl iodide under palladium catalysis.
