Not 1,2,3‐triphosphabutadiene but the “butterfly molecule” 3 is formed in the line reaction of 1 and 2. The bond between the bridgehead P atoms of 3 has a length of only 2.136 Å. Presumably 3 is formed by intramolecular [2+2]‐cycloaddition of the actually expected triphosphabutadiene (Aryl = 2,4,6‐tri‐ tert ‐butylphenyl).
