    Description / Table of Contents: Contributions to the Chemistry of Boron, LXVIII. Cyclic Compounds with Boron, Nitrogen, and Phosphorus as Ring Members (‘Phosphaborazines’)N-Metalated ‘triazaboradecalin’ reacts with (CIRP)2 NR′ and [Cl2P(O)]2NCH3, respectively, with ring formation yielding ‘phosphaborazines’ of the type 14. Ring closure to a B2N3P-ring system 17, is also achieved by SiN-cleavage from the BNSi-chain compound 15 with CH3P(O)Cl2, but BN-cleavage dominates. Spectroscopic data indicate the ring system 17 not to be planar, furthermore, that with the exception of 14a all other derivatives of 14 are formed in one geometric form only.
    Notes: N-Metalliertes„Triazaboradecalin“ reagiert mit ( (CIRP)2 NR′ bzw. [Cl2P(O)]2NCH3 unter Ringschluß zu„Phosphaborazinen“ des Typs 14. Die Heterocyclensynthese zu einem B2N3P-Ringsystem 17 gelingt auch durch SiN-Spaltung der BNSi-Kettenverbindung 15 mit CH3 P(O)Cl2, wobei allerdings die BN-Spaltung dominiert. Die spektroskopischen Daten legen ein nicht planares Ringsystem 17 nahe. Mit Ausnahme von 14a werden alle Derivate von 14 in geometrisch einheitlicher Form erhalten.
