Abstract: Abstract of the Disclosure Halogen-contianing compounds represented by the formula   .... (I) wehrein X represents a halogen atom, W represents an oxygen atom, sulfur atom or group -OCH2-, Z1 and Z2 each represent a nitrogen atom or group CH, but when Z1 is a nitrogen atom, Z2 represents nitrogen atom or group CH and when Z1 is a group CH, Z2 represents a nitrogen atom, R1 and R2 each independently represent either a hydrogen atom, halogen atom or mono- or dilower alkyl-substituted amino, or a lower alkyl, lower alkoxy or lower alkylthio each of which may be substituted with a halogen atom, R3 and R4 each independently represent a hydrogen atom, halogen atom, hydroxycarbonyl, lower alkoxycarbonyl, lower alkyl, lower alkenyl, lower alkynyl, aryl or aralkyl, or R3 and R4 form together with the carbon atoms to which they bind respectively a 5- to 8-membered carbon ring or heterocycle and these rings may optionally be substituted with one or the same or different two of hydroxy, lower alkyl, lower alklenyl, lower alkynyl, lower alkoxy, lower alkoxycarbonyl, lower alkylcarbonyloxy and a group = O, and may have un-saturated bons(s) therein, R5 reprerents a hydrogen atom or lower alkyl group, or may form together with part of R3 a double bond, A represents an oxygen atom, sulfur atom or group = N-B wherein B represents hydroxy or lower alkyl-carbonyloxy, or lower alkoxy optinally substituted with hydroxycarbonyl or lower alkoxycarbonyl, and Y either represents a hydrogen atom, a hydroxy, a mercapto, or a lower alkoxy, lower alkenoxy, lower alkynoxy, lower alkylthio, aryloxy, analkyloxy, arylthio, aralkyl-thio, lower cycloalkoxy, lower cycloalkenyloxy, pyridylthio, furylmethyloxy, furylthio or thienyloxy each optionally substituted with a halogen atom, hydroxy, lower alkyl, lower alkoxy, lower alkylthio, lower alkoxy-carbonyl, lower alkylcarbonyl, cyano, nitro or azido, or an azido, a trilower alkyl-substituted silyloxy or an imidooxy, or represents a qroup               or                   [wherein R5 and R6 each independently represent a hydrogen atom, lower alkyl, lower alkoxy, aryl or aralkyl, or R5 and R6 may form together with the carbon atom to which they bind a lower cycloalkane ring, and R8 and R9 each independently represent a hydrogen atom, a hydroxy, a lower alkyl, a lower alkenyl, a lower alkynyl, a lower alkoxy, a lower alkyl-carbonyloxy, a cyano, a lower alkylsulfonyl optionally substituted with a halogen atom, a lower alkyl sub-stituted with lower alkoxycarbonyl, a lower alkyl substituted with hydroxycarbonyl, a lower alkoxy sub-stituted with lower alkoxycarbonyl, a lower alkoxy substituted with hydroxycarbonyl, or an aryl, aralkyl, aryloxy, aralkyloxy, and arylcarbonyloxy, pyridyl, group        , group       , group         or   group       (wherein Z3 represents an oxygen atom, group CH or sulfur atom, Z4 represents a nitrogen atom or group CH, Z1 and Z2 are as defined above, and m represents an integer of 0 or 1) each optionally substituted with a halogen atom, hydroxy, lower alkyl, lower alkoxy, lower alkyl substituted with halogen atoms, cyano, nitro, amino, mono- or dilower-alkyl-substituted amino or lower alkoxycarbonyl, a group       (wherein R10 and R11 each represent a hydrogen atom, a lower alkyl, a lower alkoxycarbonyl, a lower alkyl sub-stituted with lower alkoxycarbonyl, a lower alkyl substituted with hydroxycarbonyl, or an aryl, aralkyl, pyridyl or benzothiazolyl each optionally substituted with a halogen atom, lower alkyl, lower alkyl substituted with a halogen atom, lower alkoxy, cyano, amino or nitro)], and salts thereof.
