Abstract
A sterically protected 1,4-diphospha-1,3-butadiene was prepared from t he copper-mediated coupling reaction of 2,2-dichloro-1-(2,4 ,6-tri-t-b utylphenyl)-1-phosphaethene. The X-ray crystallographic analysis shows that the molecule has a center of symmetry and that each of the bulky phenyl groups tilts almost perpendicularly to the diphosphabutadiene system serving as a good protecting group.
