  A highly efficient Suzuki cross-coupling reaction between benzylic halides and aryl boronic acids using palladium chloride as catalyst in acetone:water (3:1) as the solvent system has been developed. High yields of products, mild reaction conditions and short reaction times in the absence of ligand are important features of this method.

  A selective electrochemical oxidation was developed under mild condition. Various mono-carbonyl and multi-carbonyl compounds can be prepared from different aromatic hydrocarbons with moderate to excellent yield and selectivity by virtue of this electrochemical oxidation. The produced carbonyl compounds can be further transformed into α-ketoamides, homoallylic alcohols and oximes in a one-pot reaction

  在温和条件下开发了选择性电化学氧化。凭借这种电化学氧化，可以从不同的芳烃以中等至优异的产率和选择性制备各种单羰基和多羰基化合物。生成的羰基化合物可以在一锅反应中进一步转化为α-酮酰胺、高烯丙醇和肟。特别是，在单锅连续电解中制备了一系列 α-酮酰胺。机理研究表明，2,2,2-trifluoroethan-1-ol (TFE) 可以与催化剂物种相互作用并生成相应的氢键配合物，以提高电化学氧化性能。
• Convulsive Status Epilepticus in Children with Intractable Epilepsy is Frequently Focal in Origin

  Convulsive status epilepticus (CSE) is a common neurological emergency. Our objectives were to study children with recurrent nonfebrile CSE to assess the evidence for focal origin.

  Series of 18 children with recurrent CSE and intractable epilepsy were identified by chart review. Clinical, radiological, and EEG data were reviewed. Focal structural abnormalities were identified on MRI and CT images by one neuroradiologist who was unaware of the clinical details.

  The patient's ages ranged between 6-22 years (mean 15.3, SD 4), and 67% were males. Most children (89%) had a severe cognitive and / or behavioural disorder. Most patients (89%) had multiple seizure types and 95% of these were partial seizures. Twelve (67%) children had at least one episode of CSE with focal features identified clinically. Focal brain abnormalities were detected on 18% and 55% of CTand MRI films respectively. Overall, 53% had a focal abnormality on structural neuroimaging. Interictal EEG revealed focal or multifocal abnormalities on at least one occasion in 94% and 22% of patients respectively. Overall, 17 patients had focal features on at least one EEG. Thirteen ictal EEGs were recorded on 11 (61%) patients. Ten (91%) of these recordings revealed a focal onset.

  Many handicapped children with recurrent CSE have focal clinical, radiological, or electrographic features. This supports a focal origin for CSE in most children with intractable epilepsy.

  背景：惊厥性癫痫状态（CSE）是一种常见的神经系统急症。我们的目的是研究反复发作的非发热性CSE患儿，以评估病灶起源的证据。方法：通过病历审查确定了18名反复发作的CSE和难治性癫痫患儿。回顾了临床、放射学和脑电图数据。结果：患者年龄在6-22岁之间（平均15.3岁，SD为4），67%为男性。大多数儿童（89%）患有严重的认知和/或行为障碍。大多数患者（89%）有多种癫痫发作类型，其中 95% 为部分性癫痫发作。12名患儿（67%）至少有一次CSE发作，临床上发现其具有局灶性特征。分别有 18% 和 55% 的 CT 和核磁共振成像片检测到局灶性脑部异常。总体而言，53%的患儿在神经结构影像学检查中发现局灶性异常。分别有 94% 和 22% 的患者在发作间期脑电图上发现至少一次局灶性或多灶性异常。总体而言，17 名患者至少有一次脑电图出现局灶性特征。11 名患者（61%）记录了 13 次发作期脑电图。结论：许多复发性 CSE 的残障儿童具有局灶性临床、放射学或电图特征。这支持了大多数难治性癫痫患儿的CSE起源于病灶。

  The replacement of liquid acid catalyst by solid acids for the Friedel-Crafts reaction of aromatic alkylation is a challenging task. Mixed oxide possessing spinel structures were found to catalyze the Friedel-Craft benzylation of arenes. It was found that the reaction was very fast at 80 °C, hence the reaction was studied with respect to more substrate. The significant point was even at this temperature

  用固体酸代替液体酸催化剂用于芳族烷基化的傅克反应是一项具有挑战性的任务。发现具有尖晶石结构的混合氧化物催化芳烃的傅-克苄基化。发现反应在 80 °C 时非常快，因此研究了更多底物的反应。重要的一点是即使在该温度下也实现了以对位异构体为主的单苄基化。采用共沉淀法制备混合氧化物，并采用XRD技术对其进行表征。
