    Description / Table of Contents: Zusammenfassung Bei der Aminoborierung von Carbonylsulfid erfolgt 1,2-Addition an die Carbonylgruppe, wobei in Tris(dimethylamino)boran zwei der B−N-Bindungen, in Bis(dimethylamino)chlorboran nur eine B−N-Bindung reagieren. In Tris(2,2-dimethylhydrazino)boran reagieren alle drei B−N-Bindungen mit CO2; mit CS2 erfolgt unter den gleichen Bedingungen keine Reaktion. Mit Phosgen und Thiophosgen reagiert Tris(dimethylamino)boran unter Bildung von Bis(dimethylamino)chlorboran und substituierter Carbamide.
    Notes: Abstract Upon aminoboration of carbonyl sulfide 1,2-addition to the carbonyl group is observed. In tris(dimethylamino)borane insertion into two of the B−N bonds occurs, while in bis(dimethylamino)chloroborane only one B−N bond reacts with OCS. In tris(2,2-dimethylhydrazino)borane all three B−N bonds react with CO2, while with CS2 no insertion reaction is observed under comparable conditions. Tris(dimethylamino)borane reacts with phosgene and thiophosgene with formation of bis(dimethylamino)chloroborane and substituted carbamides.

    Notes: Abstract PhthalocyaninesPc−Me(III)X andPc−Me(V)X 3 were obtained by reacting anhydrous metal halides with phthalodinitrile and di-lithium-phthalocyanine, resp. A phthalocyanine containing niobium(V) was prepared for the first time. Mass spectrometric investigation of the products formed show the molecular ion in the case of chloro-aluminum-, chloro-indium- and tribromo-niobium-phthalocyanine. The mass spectra of chloro-scandium-, chloro-yttrium- and tribromo-tantalum-phthalocyanine showed neither peaks of the molecular mass nor metal containing fragments of the phthalocyanine structure. Mass spectrometric results seem to depend critically on the purity of the compounds employed.

    Notes: Abstract Both 4-aminobenzonitrile and 3-aminobenzonitrile react with halogenoboranes to yield mainly the corresponding amine-halogenoboranes and further products derived from the latter by elimination of hydrogen halide. In contrast, reaction between halogenoboranes and 2-aminobenzonitrile leads to insertion of the nitrile group into one of the B-halogen bonds. Derivatives of the 1.3.2-diazaboranaphthalene ring result from reactions of the insertion products with the amino group with or without elimination of hydrogen halides.

    Description / Table of Contents: Zusammenfassung Aus Halogenboranen und Organohalogenboranen (RBX 2∶R=C6H5, Cl, Br;X=F, Cl, Br) sowie aus Organoboranen oder Thioboranen entstehen mit Phthalodinitril Triisoindolo-[1,2,3-cd∶1′,2′,3′-gh∶1″,2″,3″-kl][2,3a,5,6a,8,9a,9b]-hexaazaboraphenalene von denen die B−Cl- und B−F-Verbindungen näher charakterisiert werden. Dekaboran(14), Diboran(6) oder Boranaddukte von Stickstoffbasen liefern hingegen mit Phthalodinitril metallfreies Phthalocyanin.
    Notes: Abstract Triisoindolo[1,2,3-cd∶1′,2′,3′-gh∶1″,2″,3″-kl][2,3a,5,6a,8, 9a,9b]-hexaazaboraphenalenes are obtained from the reactions of haloboranes and organohaloboranes (RBX 2∶R=C6H5, Cl, Br;X=F, Cl, Br) as well as from organoboranes or thioboranes with phthalodinitrile. The B−Cl and B−F compound have been characterized by analyses, i.r.-, u.v.- and mass-spectrometry. Diborane(6), dekaborane(14) and amine-boranes, however, upon reaction with phthalodinitrile lead to high yields of metal free phthalocyanine.

    Notes: Abstract While the reactions of N-diethylaminopropyne, methacrylonitrile and N-benzylidenemethylamine with organoboranes lead to addition of the latter across the multiple bond, methacrylonitrile and N-benzylidenemethylamine react with trichloroborane to yield adducts only.
