A method for preparing a compound of the formula ##STR1## wherein Q is C--H or N; R.sup.1 is C.sub.1-C.sub.4 alkyl, benzyl or p-nitrobenzyl and X and Y are independently selected from fluoro and chloro comprising reacting a compound of the formula ##STR2## wherein Q is >C--H or N; X and Y are independently selected from fluoro and chloro; and Z is fluoro, chloro, 1-imidazolyl or substituted 1-imidazolyl, wherein the 1-imidazolyl group is substituted with one or two substituents independently selected from C.sub.1 to C.sub.4 alkyl, with a compound of the formula [M.sup.n+ ].sub.p [V.sup.p- ].sub.n wherein M is an alkaline earth metal, Cu or Mn, n is 2, V.sup.p-, wherein p is 1 or 2, is an anion of the formula ##STR3## or a dianion of the formula ##STR4## and R.sup.1 is C.sub.1 to C.sub.6 alkyl or paranitrobenzyl, with the proviso that when Z is 1-imidazolyl or substituted 1-imidazole, M is magnesium, copper or manganese and with the proviso that when Z is fluoro, chloro or bromo, V.sup.p- is a dianion of the formula V(b).
一种制备化合物的方法,其化学式为##STR1##其中Q为C--H或N;R.sup.1为C.sub.1-C.sub.4烷基、苄基或对硝基苄基,X和Y分别选自氟和氯,包括反应化合物的方法的步骤##STR2##其中Q为>C--H或N;X和Y分别选自氟和氯;Z为氟、氯、1-咪唑基或取代的1-咪唑基,其中1-咪唑基上取代有一个或两个取自C.sub.1到C.sub.4烷基的取代基,与化合物反应的是化学式为[M.sup.n+ ].sub.p [V.sup.p- ].sub.n的化合物,其中M为碱土金属、铜或锰,n为2,V.sup.p-,其中p为1或2,是化学式为##STR3##的阴离子或化学式为##STR4##的二阴离子,R.sup.1为C.sub.1到C.sub.6烷基或对硝基苄基,但是当Z为1-咪唑基或取代的1-咪唑基时,M为镁、铜或锰,并且当Z为氟、氯或溴时,V.sup.p-为化学式V(b)的二阴离子。
