消毒是饮用水处理过程中的重要步骤,但普遍采用的氯系消毒剂在杀灭细菌病毒的同时,能产生大量具有“三致”效应的卤代消毒副产物(DBPs),严重威胁了饮用水的化学安全.研究人员已在饮用水中陆续检测并识别出700多种DBPs,但这些已知DBPs均为分子量小于800 Da的低分子量DBPs,目前对高分子量DBPs的认识还较为有限.本研究建立了基于基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)的高分子量DBPs检测方法,发现在基质为2,5-二羟基苯甲酸,阳离子化试剂为三氟乙酸钠,使用三明治法点靶,反射-正离子模式,90%激光强度时,信噪比和信号重现性达到最优,信噪比之和达到了136.2,变异系数(CV)则为4.77%.利用上述方法,在模拟饮用水中检测到5种新的高分子量DBPs.在此基础上,通过同位素模式分析、TOF/TOF串联质谱和数据库验证,建立了针对未知高分子量DBPs的分子式/结构式识别方法,确定新的高分子量DBPs为寡糖羧酸类物质.

关键词：高分子量消毒副产物基质辅助激光解吸电离飞行时间质谱阳离子化试剂检测识别

Catalytic bicyclization cascades of oxygen-tethered 1,7-enynes with simple cycloalkanes or aryl sulfonhydrazides have been established via subsequent multiple C-C bond-forming events from alkynyl/alkenyl functions, delivering a series of densely functionalized tetracyclic chromen-2-ones in a functional-group-compatible manner. In the former, Fe-catalyzed spiro-bicyclization involves radical addition, 6-exo-dig cyclization, H-abstraction and 5-endo-trig cyclization sequences under mild conditions, resulting in new spiro-fused cyclopenta[c]chromen-2-ones via dual α,α-C(sp3)-H abstractions. The latter enables in-situ sulfonylation and desulfonylation of oxygen-tethered 1,7-enynes to realize the construction of multiple C-C bonds, thereby leading to the formation of naphtho[2,3-c]chromen-6-ones.

关键词： bicyclization radical reaction 1 7-enynes fused chromen-2-ones C(sp3)-H functionalization
