A metal extractant comprising Formula (1) wherein R5, R6, R7 and R8 each independently are hydrogen, an optionally substituted hydrocarbyl group, an electron withdrawing group, an electron donating group, or one or more of R5 & R6, R6 & R7, R7 & R8 are linked in such way as to form an optionally substituted ring; Y is N or CR9 wherein R9 is hydrogen, an optionally substituted hydrocarbyl, optionally substituted hydrocarbyloxy, optionally substituted hydrocarbyloxycarbonyl, optionally substituted hydrocarbylcarbonyloxy group, optionally substituted optionally substituted mono or dihydrocarbylaminocarbonyl group; Z is N or CR10 wherein R10 is hydrogen, an optionally substituted hydrocarbyl, optionally substituted hydrocarbyloxy, optionally substituted hydrocarbyloxycarbonyl, optionally substituted hydrocarbylcarbonyloxy group, optionally substituted optionally substituted mono or dihydrocarbylaminocarbonyl group; and tautomers or salts thereof, with the proviso that both Y and Z could be N provided that no more than one of Y or Z is N.
一种金属萃取剂,包括式(1),其中R5,R6,R7和R8各自独立地是氢,可选择性取代的烃基,电子吸引基团,电子给予基团,或其中一个或多个R5和R6,R6和R7,R7和R8以形成可选择性取代的环的方式连接; Y是N或CR9,其中R9是氢,可选择性取代的烃基,可选择性取代的烃氧基,可选择性取代的烃氧羰基,可选择性取代的烃羰氧基基团,可选择性取代的单烃基或双烃基氨基羰基基团; Z是N或CR10,其中R10是氢,可选择性取代的烃基,可选择性取代的烃氧基,可选择性取代的烃氧羰基,可选择性取代的烃羰氧基基团,可选择性取代的单烃基或双烃基氨基羰基基团; 其中互变异构体或其盐,但前提是Y和Z都可以是N,只要Y或Z中不超过一个是N。
