    日期:1999.2.2
    cyclo-(F3C)2B–CR1R2–NMe2 [R1 = R2 = C6H5 (2a); R1/R2 = C12H8 (2b); R1 = H, R2 = C6H5 (2c), 4-FC6H4 (2d), 3-FC6H4 (2e), 2-FC6H4 (2f), C6F5 (2g), iPr (2h), tBu (2i); R1 = Me, R2 = C(=O)OMe (2j), C(=O)OEt (2k)] have been obtained from (F3C)2BNMe2 (1) and diazomethanes R1R2CN2. In contrast to compound 2a, the B–N bonds of 2b–2k hydrolyze to form the zwitterionic species Me2NH–CR1R2–B(CF3)2OH (3b–3k). The

  • The alkylation and ring-expansion of chromones by diazoalkanes; reluctance of oxygen to engage in sigmatropic shifts
    作者:Francis M. Dean、Robert S. Johnson
    DOI:10.1039/p19810000224
    日期:——
    In general, chromones activated by electron-withdrawing groups at position 3 are alkylated (at position 2) by diazoalkanes in the same manner as the isomeric coumarins. For example, 6-methylchromone-3-carbonitrile (3a) is converted by diazoethane into 2-ethyl-6-methylchromone-3-carbonitrile (3c). 2-Diazopropane affords cyclopropane by-products as well, and a 3-formyl group usually suffers homologation
    通常,在3位被吸电子基团活化的色酮以与异构香豆素相同的方式被重氮烷烃烷基化(在2位)。例如,通过重氮乙烷将6-甲基色酮-3-甲腈(3a)转化为2-乙基-6-甲基色酮-3-甲腈(3c)。2-重氮丙烷也可提供环丙烷副产物,并且3-甲酰基通常会与适当的酮发生同系化反应,就像2-重氮丙烷将3-甲酰基-6-甲基色酮转化为2-异丙基-6-甲基-3-(甲基丙酰基)色酮(8)。与香豆素化学形成鲜明对比的是,没有扩环成1-苯并氧杂庚酮系列。
  • Unusually Coordinated Phosphorus Compounds; 7<sup>1</sup>. Adamant-1-ylmethylidynephosphine, A New, Stable Phosphaalkyne
    作者:T. Allspach、M. Regitz、G. Becker、W. Becker
    DOI:10.1055/s-1986-31467
    日期:——
    The reaction of tris[trimethylsilyl]phosphine (4a) as well as of the lithium bis[trimethylsilyl]phosphide·; tetrahydrofuran complex (4b) with 1-adamantoyl chloride (5) results in the formation of the phosphaalkene 7 in 67% or 96% yield, respectively. Subsequent sodium hydroxide or tetra-n-butylammonium fluoride-catalysed elimination of hexamethyldisiloxane from 7 at 20/90 °C gives rise to the phosphaalkyne 8 in 83 or 71% yield. The phosphaalkyne 8 undergoes smooth [3 + 2]cycloaddition reactions with 1,3-dipoles such as the nitrile oxide 9, the diazo compounds 12a-c, and the azide 15 to produce the phospholes 11,14a-c, and 16, respectively. The phosphaalkene 7 reacts with the dipoles 9 and 12a to give the same cycloadducts 11 and 14a, respectively. In these two reactions, the primary adducts undergo spontaneous (10 → 11) or sodium hydroxide-catalysed (13 → 14a) elimination of hexamethyldisiloxane.
    三[三甲基硅基]膦 (4a) 以及双[三甲基硅基]膦锂四氢呋喃络合物 (4b) 与 1- 金刚烷酰氯 (5) 反应生成膦烃 7,收率分别为 67% 或 96%。随后,在 20/90 ℃条件下,用氢氧化钠或四正丁基氟化铵催化消除 7 中的六甲基二硅氧烷,得到膦炔 8,收率分别为 83% 或 71%。膦炔 8 与 1,3-二极(如氧化腈 9、重氮化合物 12a-c 和叠氮化物 15)发生平滑的 [3 + 2] 环加成反应,分别生成膦孔 11、14a-c 和 16。膦烯 7 与偶极 9 和 12a 反应,分别生成相同的环加成物 11 和 14a。在这两个反应中,初级加合物会自发(10 → 11)或在氢氧化钠催化下(13 → 14a)消除六甲基二硅氧烷。
  • Titration of Nonstabilized Diazoalkane Solutions by Fluorine NMR
    作者:Victor L. Rendina、Jason S. Kingsbury
    DOI:10.1021/jo202214e
    日期:2012.1.20
    A new protocol for titrating nonstabilized diazoalkane solutions by quantitative 19F NMR is reported. An excess of 2-fluorobenzoic acid dissolved in CDCl3 is treated with the diazoalkane solution at a low temperature, immediately forming the corresponding 2-fluorobenzoate ester upon warming. A significant difference in the 19F chemical shift between the ester and acid is seen, allowing facile and accurate
    报道了通过定量19 F NMR滴定不稳定的重氮烷溶液的新方案。用重氮烷溶液在低温下处理溶解在CDCl 3中的过量的2-氟苯甲酸,在加热后立即形成相应的2-氟苯甲酸酯。观察到酯和酸之间在19 F化学位移方面存在显着差异,从而可以轻松,准确地积分来确定滴度。该过程安全,快速,并且可以高精度指示活性重氮烷浓度。
  • N−N Bond Cleavage in Diazoalkanes by a Bis(imino)pyridine Iron Complex
    作者:Sarah K. Russell、Emil Lobkovsky、Paul J. Chirik
    DOI:10.1021/ja8075132
    日期:2009.1.14
    Addition of monosubstituted diazoalkanes, N(2)CHR (R = Ph, p-Tolyl, (t)Bu, Cy), to the bis(imino)pyridine iron dinitrogen complex, ((iPr)PDI)Fe(N(2))(2), at 23 degrees C in benzene-d(6) resulted in rapid cleavage of the N-N bond to yield the iron nitrile and imine complexes, ((iPr)PDI)FeNCR and ((iPr)PDI)FeHNCHR, respectively. Aryl azines were also cleaved with ((iPr)PDI)Fe(N(2))(2) and yielded the
    将单取代重氮烷烃 N(2)CHR (R = Ph, p-Tolyl, (t)Bu, Cy) 添加到双 (亚氨基) 吡啶铁二氮络合物 ((iPr)PDI)Fe(N(2) )(2),在 23 摄氏度的苯-d(6) 中导致 NN 键快速裂解,分别产生铁腈和亚胺配合物 ((iPr)PDI)FeNCR 和 ((iPr)PDI)FeHNCHR . 芳基吖嗪也被 ((iPr)PDI)Fe(N(2))(2) 裂解并产生相同的产物。机理研究支持这样一种途径,即首先形成亚烷基亚铁,然后与另一当量的重氮烷快速 [4pi + 2pi] 环加成。随后确定速率的 1,3-氢迁移,然后是逆环加成产生观察到的产物。
