  general method is presented for the synthesis of alkylated arenes by the chemoselective combination of two electrophilic carbons. Under the optimized conditions, a variety of aryl and vinyl bromides are reductively coupled with alkyl bromides in high yields. Under similar conditions, activated aryl chlorides can also be coupled with bromoalkanes. The protocols are highly functional-group tolerant (−OH,

• An Unusual Presentation of Tarsal Tunnel Syndrome Caused by an Inflatable Ice Hockey Skate

  Tarsal tunnel syndrome is a rare form of entrapment neuropathy. In athletes, it is usually the result of repetitive activity, local injury or a space-occupying lesion. Rarely, athletic footwear has been described as the primary cause of this syndrome.

  A 37-year-old male recreational hockey player was examined clinically and electrophysiologically because of spreading numbness in the toes of his left foot while playing hockey and wearing inflatable ice hockey skates designed to promote a better fit.

  Clinical and electrophysiological studies revealed evidence of left medial and lateral plantar nerve involvement. Reduced amplitudes of mixed and motor plantar nerve responses with fibrillation potentials and positive sharp waves and no evidence of conduction block suggest that the primary pathology was axonal loss. Follow-up examination showed significant clinical and electrophysiological improvement after the patient stopped wearing his inflatable ice hockey skates.

  We report an unusual case of tarsal tunnel syndrome caused by an inflatable ice hockey skate. The patient improved clinically and electrophysiologically when he stopped wearing the boot.

  背景：跗骨隧道综合征是一种罕见的局限性神经病。在运动员中，它通常是重复性活动、局部损伤或空间占位性病变的结果。方法：对一名 37 岁的男性休闲曲棍球运动员进行了临床和电生理学检查，原因是他在打曲棍球时左脚脚趾麻木，而他穿的充气冰上曲棍球冰鞋是为了更好地贴合脚部。混合性和运动性足底神经反应的振幅减小，并伴有颤动电位和正尖波，没有传导阻滞的证据，这表明主要病理变化是轴索缺失。随访检查显示，患者在停止穿着充气冰球冰鞋后，临床和电生理状况均有明显改善。结论：我们报告了一例因冰上曲棍球充气冰鞋引起的不寻常的跗骨隧道综合征，患者在停穿该冰鞋后，临床症状和电生理症状均有所改善。

• Synthetic studies on 4,5-dihydro-3H-1,2,4-triazole-3,5-diones bearing fluorogenic residues at N-4
  作者：Gordon Read、Nigel R. Richardson

  DOI：10.1039/p19960000167

  日期：——

  A number of fluorescent 4,5-dihydro-3H-1,2,4-triazole-3,5-diones have been made. Intra-inter-electrophilic substitution by the triazoledione moiety on the activated naphthalene ring of 4-[6-(5-dimethylamino-1-naphthylsulfonamido)hexyl]-4,5-dihydro-3H-1,2,4-triazole-3,5-dione 4a3 leads to rapid decomposition. The dienophilicity of the triazoledione moiety in 4-pyren-1-yl-4,5-dihydro-3H-1,2,4-triazole-3,5-dione 4d is dramatically lowered by steric shielding. Insertion of a three-carbon spacer unit into the latter compound, to give the 3-pyren-1-ylpropyl analogue 4e, affords a valuable fluorogenic reagent for the analysis of trace levels of 1,3-dienes. Powdered barium manganate is shown to be an excellent solid-phase oxidant for conversion of urazoles into 1,2,4-triazole-3,5-diones.

  已经合成了一些荧光的4,5-二氢-3H-1,2,4-三唑-3,5-二酮。在4-[6-(5-二甲氨基-1-萘磺酰胺)己基]-4,5-二氢-3H-1,2,4-三唑-3,5-二酮4a3的活化萘环上，三唑二酮基团的内外电亲核取代反应导致快速分解。4-芘-1-基-4,5-二氢-3H-1,2,4-三唑-3,5-二酮4d中的三唑二酮基团的二烯亲和性因空间位阻而显著降低。在后者化合物中插入一个三碳间隔单元，生成3-芘-1-基丙基类似物4e，为分析微量1,3-二烯提供了一种有价值的荧光试剂。粉末状锰酸钡被证明是一种优良的固相氧化剂，可以使尿唑转化为1,2,4-三唑-3,5-二酮。

  photocatalyst ([Ru(bpy)3]2+) bound to a protein ligand was essential for the title method. Local single‐electron transfer from the catalyst resulted in the formation of tyrosyl radicals. N′‐Acetyl‐N,N‐dimethyl‐1,4‐phenylenediamine was used as the tyrosyl radical trapping agent and used in a radical addition to afford selective modification of the target protein.
