标题:使用 Cf3+ 进行化学电离:高效检测小烷烃和碳氟化合物
摘要:在紧凑型傅里叶变换离子回旋共振 (Fticr) 质谱仪中,三氟甲基离子 Cf3+ 被评估为化学电离 (Ci) 前体.它通过氢化物提取与烷烃反应,允许对高达 C4 和环状的烷烃进行表征和量化.对于较大的烷烃,会发生碎裂.碳氟化合物通过提取氟化物进行反应.已经测量了与烷烃,氟烷烃,氯氟烷烃以及几种常见 Voc 反应的速率系数.使用 Cf3+ 进行空气中的痕量分析已经在含有痕量丙酮,甲苯,苯和环己烷的空气样品上进行了测试.结果与使用 H3O+ 前体获得的结果一致,并允许额外的环己烷定量.

权利人:TRUSTEES OF THE LELAND STAMFOR
摘要:Synthesis of acids R1COOH and amides R1CONR2R3 wherein R1 is attached to the carbonyl group by an aliphatic carbon atom and R2 and R3 are hydrogen or organic groups of a primary or secondary amine, by forming an alkyl or acyl intermediate (R1Fe(CO) 4 or R1COFe(CO) 4) and treating the intermediate with a suitable cleaving agent and, in the case of amides, also with ammonia or an amine.

标 题 :Green chemistry synthesis of the malaria drug amodiaquine and analogs thereof
发明人：FORTUNAK JOSEPH MARIAN; KULKARNI AMOL ANANT; KING CHRISTOPHER

摘要:Methods are provided for a green chemistry one-pot synthesis of amodiaquine and amodiaquine analogs. The methods have a lower environmental impact, lower investment cost, reduced amounts of byproducts and impurities, and a shorter synthesis time, compared to current conventional synthesis methods. The methods reduce the total number of steps in the synthesis from four to five down to two, thereby simplifying production; and allow a reduced number of solvents and reagents to be used in production, thereby reducing the waste generated in the synthesis. The methods can reduce the waste to about 3-5 kilograms of waste generated per kilogram of product produced; and surprisingly improve the overall yield from 60-65% to greater than 90% as compared to the current conventional synthesis methods for amodiaquine and its analogs.
