Hydrogenolysis of 8 over a platinum catalyst furnished 1,3,5,7-tetraisopropyladamantane (9) in quantitative yield. 1-Isopropyladamantane (3) as well as the hydrocarbons 4-7 did not give any crystals suitable for X-ray crystal structure analysis, even when using the Optical Heating and Crystallization Device (OHCD). This method was rather successful when applied to the tetravinyl derivative 17, X-ray crystal structure analysis of which revealed an approximately C-2- symmetric conformation in the solid state at 150 K However, no well-defined orientation was detected for the cyclopropyl groups in 8, and the molecules were severely disordered even at 30(1) K. In contrast to this, X-ray crystal structure analysis of the tetraisopropyl derivative 9 revealed an S-4-symmetric conformation for this hydrocarbon at 203 K. ((c) Wiley-VCH Verlag GmbH 1 Co.

Their surprisingly high specific rotations are well reproduced by DFT/SCI computations and stem from the fact that these hydrocarbons essentially are sigma-helicenes (i.e., rigidly held helical arrangements of sigma-bonds). Some light is shed on the properties of radical cations derived from [3]- and [4]rotanes. While the former adopts C-s or C-2v symmetry, the latter retains the D-4h symmetry of the neutral hydrocarbon, according to high-level computations. Experimental and computational evidence is also presented that the anti-aromatic cyclopentadienyl cation is stabilized as a singlet ground state by five cyclopropyl substituents. Yet, the three cyclopropyl groups in tricyclopropylamine do not favor the formation of its radical cation, because they are not in the proper orientation. When this amine radical cation is generated by cobalt gamma-irradiation in a Freon matrix, evidence for a significant conformational change is obtained by EPR spectroscopy. Finally, the conformational dynamics of the newly prepared crowded molecules tetracyclopropyl- and tetraisopropyl-methane are discussed."],["dc.identifier.doi","10.1351/pac200375050549"],["dc.identifier.isi","000183076200003"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/46051"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Int Union Pure Applied Chemistry"],["dc.publisher.place","Res triangle pk"],["dc.relation.conference","16th International Conference on Physical Organic Chemistry (ICPOC-16)"],["dc.relation.eventlocation","SAN DIEGP, CALIFORNIA"],["dc.relation.issn","0033-4545"],["dc.title","New structurally interesting cyclopropane derivatives.

The starting 4-trimethylsilyl-(9b) and 4-(trimethylsilyloxymethyl)snoutene (9d) were prepared from the correspondingly substituted cyclooctatetraenes 4b and 4c in several steps in 20 and 8% overall yields, respectively.

Rough kinetic measurements of these rearrangements indicate some acceleration of the reaction caused by the presence of a methyl substituent and retardation by that of a trimethylsilyl substituent, relative to the parent diademane 1a.

In the substituted cyclopropane ring, the two proximal bonds are lengthened (1.530 Angstrom) and the distal bond is slightly shortened (1.492 Angstrom). This indicates a small, but significant electron-withdrawing effect of the trimethylsilyl group in 9b.
