Synthesis of novel aza-heterocyclic derivatives from diester and diacid chlorides having the dibenzobarrelene skeleton

When attempting to synthesize the symmetric aza-heterocyclic-substituted dibenzobarrelene derivatives from the 2-aminobenzimidazole (or 2-aminoimidazoline) with diacid chlorides and diester in the presence of various organic bases, different products were isolated in high yield. NMR spectroscopic analysis proved these products to be dibenzobarrelene-substituted fused benzimidazodiazepine, imidazolinediazepine, and dicarboxamides derivatives. Cyclic or noncyclic dicarboxamides with the dibenzobarrelene skeleton have been synthesized for the first time using these methods.

Importance of C*-H based modes and large amplitude motion effects in vibrational circular dichroism spectra: The case of the chiral adduct of dimethyl fumarate and anthracene

The role played by the C-H based modes (C* being the chiral carbon atom) and the large amplitude motions in the vibrational absorption (VA) and vibrational circular dichroism (VCD) spectra is investigated. The example of an adduct of dimethyl fumarate and anthracene, i.e., dimethyl-(+)-(11R,12R)-9,10- dihydro-9,10-ethanoanthracene-11,12-dicarboxylate, and two deuterated isotopomers thereof specially synthesized for this goal, are considered. By comparing the experimental and DFT calculated spectra of the undeuterated and deuterated species, we demonstrate that the C-H bending, rocking, and stretching modes in the VA and VCD spectra are clearly identified in well defined spectroscopic features. Further, significant information about the conformer distribution is gathered by analyzing the VA and VCD data of both the fingerprint and the C-H stretching regions, with particular attention paid to the band shape data. Effects related to the large amplitude motions of the two methoxy moieties have been simulated by performing linear transit (LT) calculations, which consists of varying systematically the relative positions of the two methoxy moieties and calculating VCD spectra for the partially optimized structures obtained in this way. The LT method allows one to improve the quality of calculated spectra, as compared to experimental results, especially in regard to relative intensities and bandwidths.

Shape takes the lead: Templating organic 3D-frameworks around organometallic sandwich compounds

The novel organic-organometallic crystalline compounds [(η5- C5H5)2Co][(cis-deccaH)(cis-deccaH2)] (1), [(η5-C5H5)2Co][(cis- deccaH)(cis-deccaH2)]?H2O (2), [(η5- C5H5)2Co][trans-deccaH] (3), [(η5-C5H5)2Co][(trans-deccaH) (trans-deccaH2)] (4), [(η5-C5Me 5)2Co][cis-deccaH] (5), [(η5-C 5Me5)2Co][trans-deccaH]?4H2O (6), and [(η6-C6H6)2Cr][trans- deccaH] (7) have been prepared by direct reaction of neutral [(η5-C5H5)2Co], [(η5-C5Me5)2Co], and [(η6-C6H6)2Cr] with the organic compounds cis-9,10-dihydroanthracene-9,10-α,β-succinic acid anhydride and trans-9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylic acid (cis-decca and trans-deccaH2, respectively). The organic building blocks have been chosen because of their three-stem star-like shape and the difference in hydrogen-bonding capacity. It is shown that the formation of a honeycomb-type anionic arrangement around the organometallic cations does not require the assistance of strong hydrogen-bonding interactions. Depending on the stoichiometric ratio and on the presence of water molecules, rectangular and layered crystal packings are also obtained.
