摘要

Substd. benzene sulphonyl urea and thiourea cpds. of formula (I) and their salts are new. R1 = H, 1-7C alkyl or 3-7C cycloalkyl; R2 = H, 1-6C alkyl, 1-6C alkoxy, 1-6C mercaptoalkyl, 3-6C cycloalkyl, or 1-8C chain (in which 1-4C atoms are replaced by Het), F or Cl; R3, R4 = H, 1-12C alkyl, 3-10C cycloalkyl, 1-6C fluoroalkyl, 3-6C fluorocycloalkyl, or 1-10C chain in which 1-4C atoms are replaced by Het; or R3+R4 = (CH2)p, opt. with 1 or more CH2 replaced by heteroatoms; p = 2-8; Q, X = O or S; Y = (CR5R6)m; R5; R6 = H, Me or Et (opt. different in different CR5R6 gps.); Het = heteroatom such as O, N or S, m = 1-4.
