<p>Cpds. and their method of prepn. where Ring A is opt. substd. with is not > 3 halogen atoms atomic number = 35), is not > 3 lower alkyl groups, is not > 2 trifluoromethyl groups or substd. phenyl groups. Ring A' is opt. substd. independently as for ring A. Ring B opt. substd. with is not > 5 halogen atoms (atomic no is not > 35), is not > 3 alkyl or alkoxy groups (1-9C atoms), is not > 2 trifluoromethyl groups, a phenyl or phenoxy group which may be opt. substd. with is not > 3 halogen atoms (atomic number = 35), is not > 3 lower alkyl groups, or is not > 2 trifluoromethyl groups. R1, R2, R1', R2' = H or halogen (atomic number = 35). X1, X2, and X3 = S, O (at least one X = S). The compounds have antibacterial activity. dithiocarbonic acid O-(2-(2",4",-dichlorophenoxy)-5-chlorophenyl)-S-(4'-chlorophenyl) ester, m.p. 127-129 deg.C.</p> |
