    Description / Table of Contents: Synthesis of Triphenylphosphane-en-ynes and Phosphindoles as well as X-Ray Analyses of two PhosphindolesBy means of aminochlorophenylphosphanes triphenylphosphanes are prepared, in which the o-positions are optionally substituted by trans-phenylethenyl and phenylethinyl groups (4a - c and 5a - c). Surprisingly, the intermediate chlorophosphanes 3a and c can be rearranged thermally to the phosphindoles 6a, b and 7. The X-ray analyses of 6a and 7 reveal no significant shortening of the endocyclic P - C bonds, although there are some spectroscopic and chemical evidences of a delocalisation of the phosphorus free electron pair.
    Notes: Über Aminochlorphenylphosphane werden Triphenylphosphane hergestellt, die in o-Stellung wahlweise mit trans-Phenylethenyl- und Phenylethinyl-Gruppen substituiert sind (4a - c bzw. 5a - c). Überraschenderweise können die als Zwischenprodukte auftretenden Chlorphosphane 3a und c thermisch zu den Phosphindolen 6a, b und 7 umgelagert werden. Die Röntgenstrukturanalysen von 6a und 7 zeigen keine nennenswerte Verkürzung der endocyclischen P - C-Bindungen, obwohl es spektroskopische und chemische Hinweise auf eine Delokalisierung des freien P-Elektronenpaars gibt.
