Abstract Bis(trichlorsilyl)phenylamine (1) and 2,2,4,4-tetrachlor-l,3-diphenyl-[l,3,2,4]diazadisiletid-ine (2) have been synthesized as potential precursors for the preparation of porous oxygen-free solids by the reaction of tetrachlorosilane with dilithiated aniline. Both compounds were characterized by crystal structure analysis. 1 crystallizes monoclinically, P2/n, a = 10.124(2), b = 12.701(2), c = 11.425(3) Å, β = 109.34(2)° and Z = 4 (R1 = 4.6%, wR2 = 11.6%, 1297 independent reflections). 2 crystallizes orthorhombically, Pbca, a = 11.42(1), b = 8.17(1), c = 17.05(1)Å, and Z = 4 (R1 = 3.7%, wR2 = 8.2%, 1923 independent reflections). Ammonolyses and polycondensation of 1 and 2 yield amorphous solids with low porosities.

The reaction of 1,3-diisopropylimidazolium chloride (3) with benzylpotassium in d5-bromobenzene generates the stable carbene 1,3-diisopropylimidazol-2-ylidene that is trapped by hafnium tetrachloride. A chloride anion is subsequently added to the Hf atom of the resulting intermediate to yield the salt [(1,3-diisopropylimidazol-2-ylidene)HfCl₅−][1,3-diisopropylimidazolium+] 6 that was characterized by an X-ray crystal structure analysis.

Abstract 7-Methyl-1,3,5-triaza-7-phosphaadamantane-7-ium-tetrafluoroborate (2b) has been synthesized and characterized by crystal structure analysis. The crystal structure is interpreted in comparison with the parent compound 1,3,5-triaza-7-phosphaadamantane, and its 7-oxide and 7-sulfide. 7-Methyl-1,3,5-triaza-7-phospha-tricyclo[3,3,2,1 3,7]-undecan-7-ium-iodide (6) has been prepared and characterized by 31P, 13C, and 1H NMR spectroscopy and by its IR spectrum.
