  [10]Paracyclophanediamides and their octadehydro derivatives: novel exotopic receptors with hydrogen-bonding sites on the bridge

  摘要：

  2,9-Diaza-1,10-dioxo[10]paracyclophanes were prepared in short steps from the terephthaloyl chlorides via the corresponding 4,6-diyne derivatives, and the amide groups on the bridge endow the skeleton with the guest-binding properties as demonstrated by complexation with adrenaline by hydrogen bonds. The chiral auxiliaries on the bridge induce diastereomeric preference in terms of the planar chirality for the octadehydro derivative with a rigid diyne unit in crystal. (C) 2004 Elsevier Ltd.

  Aryl(trimethylsilyl)selenides as Reagents for the Synthesis of Mono- and Diselenoesters

  摘要：

  Silylated organoselenium reagents react under mild conditions with acid chlorides to provide a high yield route to aromatic selenoesters. The synthesis, structures, and spectroscopic properties of the selenoesters C6H5SeC(O)R (R = CH2CH3, 1; p-CH3C6H4, 2; p-C6Me4Br, 3; p-C6Me4C-(O)SeC6H5, 4) and RC(O)SeFcSeC(O)R (Fc = Fe(C5H4)(2); R = CH2CH3, 5; p-CH3C6H4, 6; p-BrC6Me4, 7) and RC(O)Se(C6H4) SeC(O)R (n = 1, R = CH2CH3, 8a; n = 2, R= CH2CH3, 8b; n = 1, R = p-CH3C6H4, 9a; n = 2, R = p-CH3C6H4, 9b; n = 1, R =p-C6Me4Br, 10a; n = 2, R = p-C6Me4Br, 10b) and C6H5SeC(O)CH2CH2C(O)SeC6H5 11 are discussed. Although 11 can be prepared in high yield from the reaction of C6H5SeSiMe3 and ClC(O)CH2CH2C(O)Cl in tetrahydrofuran solvent, similar reactions in the absence of solvent led to the competitive formation of both 11 and (C6H5Se)(3)CCH2CH2C(O)OSiMe3 12. The new selenoesters have been characterized by multinuclear NMR (H-1, C-13, Se-77), IR, and UV-vis spectroscopies, electrospray mass spectrometry, and, for complexes 2, 4, 7, 10b, and 12, single-crystal X-ray diffraction.

• Multipoint Recognition of Catecholamines by Hydrindacene-Based Receptors Accompanied by the Complexation-Induced Conformational Switching

  The molecular recognition of catecholamines by hydrindacene-based receptors 1 and 2, as well as the durene-based receptor 3, and the guest-induced conformational changes are reported. These receptors selectively bind adrenaline and dopamine salts through the guests' ammonium group and 3-hydroxyl group on the aromatic ring. In the case of adrenaline, an additional hydrogen bond with a benzylic hydroxyl

• Phosphorus Copies of PPV:  π-Conjugated Polymers and Molecules Composed of Alternating Phenylene and Phosphaalkene Moieties
  作者：Vincent A. Wright、Brian O. Patrick、Celine Schneider、Derek P. Gates

  DOI：10.1021/ja060816l

  日期：2006.7.1

  A new class of pi-conjugated macromolecule, poly(p-phenylenephosphaalkene) (PPP), is reported. PPPs are phosphorus analogues of the important electronic material poly(p-phenylenevinylene) (PPV) where PdC rather than CdC bonds space phenylene moieties. Specifically, PPPs [sC(6)R(4)-P=C(OSiMe3)sC(6)R'(4)s C(OSiMe3)=P-](n) (1: R = H, R = Me; 11: R = Me, R' = H) were synthesized by utilizing the Becker reaction of a bifunctional silylphosphine, 1,4-C6R4[P(SiMe3)(2)](2), and diacid chloride 1,4-C6R4[COCl](2). Several model compounds for PPP are reported. Namely, mono(phosphaalkene)s RsPdC(OSiMe3)s R' (4: R= Ph, R' = Mes; 7: R = Mes, R' = Ph), C-centered bis(phosphaalkene)s RsPdC(OSiMe3)-C6R'(4)-C(OSiMe3) dPsR (5: R = Ph, R' = Me; 8: R = Mes, R' = H), and P-centered bis(phosphaalkene)s R-C( OSiMe3) dPsC(6)R'4-P=C(OSiMe3) sR (6: R = Mes, R' = H; 10: R = Ph, R = Me). Remarkably, selective Z-isomer formation (i.e., trans arylene moieties) is observed for PPPs when bulky P-substituents are employed while E/Z-mixtures are otherwise obtained. X-ray crystal structures of Z-7, Z, Z-8, and Z, Z-10 suggest moderate pi-conjugation. The twist angles between the PdC plane and unsubstituted arenes are 16 degrees-26 degrees, while those between the PdC plane and methyl-substituted arenes are 59-67. The colored PPPs and their model compounds were studied by UV/vis spectroscopy, and the results are consistent with extended pi-conjugation. Specifically, weakly emissive polymer E/Z-1 (lambda(max)) 338 nm) shows a red shift in its absorbance from model E/Z-4 (lambda(max)) 310 nm), while a much larger red shift is observed for Z-11 (lambda(max) = 394 nm) over Z-7 (lambda(max) = 324 nm).
