1,2-bis[10,15-di(3,5-di-tert-butyl)phenylporphyrinatonickel(II)-5-yl]diazene was synthesised via copper-catalyzed coupling of aminated nickel(II) 5,10-diarylporphyrin ("corner porphyrin") and its X-ray crystal structure was determined. Two different crystals yielded different structures, one with the free meso-positions in a trans-like orientation, and the other with a cis-like disposition. The free meso-positions of the obtained dimer have been further functionalized while the synthesis of a zinc analog has so far been unsuccessful. The X-ray crystal structure of the dinitro derivative of the dinickel(II) azoporphyrin was determined, and the structure showed a cis-like disposition of the nitro groups.

Abstract Monomerie diiodides of 2,4,6-tri(tert-butyl)phenyl = (s-Mes), 2,4,6-triisopropylphenyl = (Trip)-and 2,4-di-tert-butyl-6-methylphenyl = (DBMP)-gallium and -indium were prepared by the reaction of the lithiated aryls with MI3 (M = Ga, In) in hexane/Et2O. s-MesInI2 (1), s-Mes2InI (2), s-MesGaI2 (3), s-Mes2GaI (4), Trip2InI (5) and (DBMP)2InI (6) were obtained and characterized by their mass and NMR spectra (1H, 13C), and/or by elemental analyses. An X-ray crystal structure analysis was carried out for 1.

Based on single crystal X-ray diffraction data the crystal structure of tricarbonyl(2,6-dwmbutyl- pyridine)chromium(0) has been determined at 200 K: space group P 21/n, Z = 4, lattice constants a = 680.6(5), b - 1383.3(10), c = 1763.0(16) pm, β = 96.53(8)°, refinement to Rw - 0.048 for 1672 independent reflections with FO > 2 σ. The chromium atom is η6π6- bonded to the essentially planar pyridine ring (Cr-C: 219-222 pm, Cr-N: 221 pm). The CO ligands show “eclipsed” orientation with respect to the 2, 4 and 6 position of the pyridine ring. Two CO groups fit into the gaps formed by two methyl groups of the tert-butyl substituents in 2 and 6 position, respectively. The results are discussed in context with related arene and λ3-phosphorine complexes

2,5-Bisdimethylamino-2,5-dihydrobenzo[b]-1,2,5-thiadiborole (2) has been obtained from the diiodine-derivative by reaction with dimethyl-aminotrimethylsilane. Reaction of 2 or 2,5-bisdimethylamino-1′,2′-dimethyl-2,5-dihydrobenzo[b]-thiadiborole with di-tert-butyl-, tertbutyl-trimethylsilyl- and bistrimethylsilyl-sulfurdiimide yields the 2,7,3,6-tetrahydrobenzo[b]-1,2,7,3,6-thiadiazadiborepines (3a-3e). 1H, 11B, 13C NMR, MS and analytical data and results of analysis are given. For 3a the X-ray structure is reported.
