Low Coordinated Phosphorous Compounds, 9. Pericyclic Reactions of Phospha-1,5-hexadiene Derivatives

Reaction of phenylbis(trimethylsilyl)phosphane (1) with phenyl isocyanide dichloride (2a) yields two diastereomeric tetraphosphahexadienes 4a (rac- and meso-form). 31P NMR temperature-run shows identically -tetraphospha Cope rearrangement to the rac-form.The meso-form was isolated (X-ray datas). 1 reacts with succinyl dichloride to yield the diphospha-1,5-hexadiene 9, which undergoes spontanously -diphospha Cope rearrangement to the divinyldiphosphane 10.
