    Description / Table of Contents: Contributions to the Chemistry of Boron, 196. - Preparation and Reaction of a 3-Amino-1,2,3-azaphosphaboriridineThe 1,2,3-azaphosphaboriridine 7, obtained by dehalogenation of the boryl(phosphino)amine precursor 6, reacts with sulfur or selenium not only with ring expansion but also with oxidation of its λ3-P atom to form the new heterocycles 8. The M(CO)5 fragments generated photolytically from Cr(CO)6 and W(CO)6, respectively, add to the P atom of 7. In contrast, MeI does not produce the phosphonium salt derived from 7. Rather the RP fragment is removed as iPr(Me)PI with formation of the iminoborane tmp-iPr.
    Notes: Das 1,2,3-Azaphosphaboriridin 7, dargestellt durch Enthalogenieren der Boryl(phosphino)amin-Vorstufe 6, reagiert mit Schwefel und Selen nicht nur unter Ringerweiterung, sondern zugleich unter Oxidation des λ3-Phosphors zu den neuen Heterocyclen 8. Während sich die aus Cr(CO)6 und W(CO)6 unter Photolyse erzeugten Pentacarbonylfragmente M(CO)5 an das P-Atom von 7 addieren, erhält man mit MeI kein Phosphoniumsalz. Vielmehr wird das RP-Fragment von 7 unter Bildung des Iminoborans tmp-tBu als iPr(Me)PI abgespalten.
