    Abstract The preparation of 4- and 5-t-Bu-pyrrole-2-aldehyde can be brought about in a high yield and purity using Vilsmeier-Haack type reactions as conclusions to reaction sequences involving a 1-benzenesulfonyl directing group on pyrrole (4-substitution) or the formamidinium salt of pyrrole (5-substitution). Azines/imines were prepared and characterised.

  • Entropic Mixing Allows Monomeric‐Like Absorption in Neat BODIPY Films

    achievable dye concentration. Here, five BODIPY derivatives containing small alkyl chains in the α‐position were synthesized and photophysically characterized. By blending two or more derivatives, the increase in entropy reduces aggregation and therefore produces films with extreme dye concentration and, at the same time almost solution like absorption properties. Such a film was placed inside an optical cavity
    分子间相互作用在材料化学中起着至关重要的作用,因为它们决定着薄膜的形态。有机染料薄膜的光物理性质对局部环境高度敏感,因此已投入大量精力来设计有机薄膜的形态。增溶的侧链可以成功地在空间上分离发色团,减少有害的分子间相互作用。但是,该策略也显着降低了可达到的染料浓度。在这里,合成了五种在α位含有小烷基链的BODIPY衍生物,并对其进行了光物理表征。通过混合两种或多种衍生物,熵的增加会减少聚集,因此会产生具有极高染料浓度的薄膜,并且 同时几乎像溶液一样具有吸收特性。这样的薄膜被放置在光学腔内,并且通过达到的染料浓度和薄膜的清晰吸收特性,证明了所实现的系统达到了强激子-光子耦合机制。

  • Synthesis, structures and reactivity of 2-phosphorylmethyl-1H-pyrrolato complexes of titanium, yttrium and zinc
    作者:Lewis M. Broomfield、Joseph A. Wright、Manfred Bochmann
    DOI:10.1039/b908394d

    The reaction of secondary phosphines HPR2 (R = Ph, Cy) with pyrrole-2-aldehydes gives a new family of 2-phosphorylmethyl-1H-pyrroles as potentially chelating mono-anionic ligands. The reaction with Ti(NMe2)4 affords octahedral Ti(NMe2)2NC4H2(4-R′)CH2P(O)R2}2 (R′ = H, But). While the diphenylphosphoryl complexes adopt a configuration with trans-pyrrolato ligands, the dicyclohexyl analogue prefers an all-cis conformation, with profound consequences on metal–ligand bonding. The reaction of sterically undemanding HNC4H3CH2P(O)Ph2 with Y[N(SiHMe2)2]3(THF)2 give the homoleptic complex Y[NC4H3CH2P(O)Ph2]3; mixed-ligand intermediates Y[N(SiHMe2)2]2(N–O) and Y[N(SiHMe2)2](N–O)2 were identifiable but could not be isolated. The bulky ligand HNC4H2(5-But)CH2P(O)Ph2 does not react with Ti(NMe2)4 but protolyses Zn[N(SiMe3)2]2 to give a 1 : 2 complex Zn(N–O)2 as the only isolable product. On the other hand, its reaction with Y[N(SiHMe2)2]3(THF)2 affords the mono-amido complex YN(SiHMe2)2}NC4H3(5-But)CH2P(O)Ph2}2 which shows good activity for the ring-opening polymerisation of cyclic esters.
    二级膦 HPR2(R = Ph, Cy)与吡咯-2-醛的反应生成了一类新的2-膦酰基甲基-1H-吡咯,作为潜在的螯合单阴离子配体。与Ti(NMe2)4的反应形成八面体Ti(NMe2)2NC4H2(4-R′)CH2P(O)R2}2(R′ = H, But)。虽然二苯膦酰基配合物采用了带有反式吡咯配体的构型,二环己基的类似物则更倾向于全顺式构象,这对属-配体结合产生了深远的影响。体积较小的HNC4H3 (O)Ph2与Y[N(SiHMe2)2]3(THF)2的反应生成了均配体络合物Y[NC4H3 (O)Ph2]3;可识别的混合配体中间体Y[N(SiHMe2)2]2(N–O)和Y[N(SiHMe2)2](N–O)2,但无法分离。体积较大的配体HNC4H2(5-But) (O)Ph2与Ti(NMe2)4不反应,但会对Zn[N(SiMe3)2]2进行质子化反应,生成唯一可分离的产物1:2络合物Zn(N–O)2。另一方面,其与Y[N(SiHMe2)2]3(THF)2的反应生成单酰胺配合物YN(SiHMe2)2}NC4H3(5-But) (O)Ph2}2,该化合物在环状酯的开环聚合中表现出良好的活性。
