    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.

    Notes: The reactions of hydrazine with tris(trimethylsilyl)aluminium-ether have been studied: Reactant ratios of 0.5:1 and 0.8:1 produce the cyclic aminoalane [(Me3Si)2AlN(H)(SiMe3)]2 (1), which is formed by N-N bond cleavage and silyl group migration from aluminium to nitrogen. Pyrolysis under NH3 of a polymeric product formed from a 1:1 reaction produces an AlN/Si3N4 composite.

    Notes: Monomeric B-[bis(trimethylsilyl)phosphanyl]-9-borabicyclo-[3.3.1]nonane (1) reacts with acyl chlorides 2 in a 1:2 ratio to afford deep red derivatives of six-membered oxaoxonia-s̰2,λD3-phosphaboratacyclohexadienes 3. In contrast, the (di-tert-butylboryloxy)phosphaethene 5 is obtained from tBu2BP-(SiMe3)2 (4) and PhC(O)Cl. It is assumed that both reactions proceed via a common intermediate, an (acylphosphanyl)bo-rane 6. The color of compounds 3, which feature a flat boat conformation, is due to a π-π* transition.
