 Title    Photosynthetic Electron Transport Inhibition by Pyrimidines and Pyridines Substituted with Benzylamino, Methyl and Trifluoromethyl Groups  
 Abstract    The decrease of the num ber of ring nitrogen atoms of 2-benzylamino-4-methyl-6-trifluoro-methyl-l,3,5-triazines on herbicidal activity and inhibition of photosynthetic electron trans­ port (PET) was assayed using thylakoids from Spinacia oleracea or atrazine-resistant Cheno­ podium album. Three 2-benzylamino-4-methyl-6-trifluoromethyl-l,3,5-triazines, nine pyrimi­ dines with a benzylamino-, methyl-and trifluoromethyl-group, 2-benzylamino-6-methyl-4-trifluoromethyl-pyridine and N-benzyl-S-methyl-S-trifluoromethylaniline were synthesized and assayed. 2-(4-Bromobenzylamino)-4-methyl-6-trifluoromethylpyrimidine exhibited the highest PET inhibitory activity against Spinacia oleracea thylakoids of all compounds tested. The 2-benzylaminopyrimidines and 2-methylpyrimidines having a 4-halobenzylamino group exhibited higher PET inhibition than atrazine and 2-trifluoromethylpyrimidines against Spi­ nacia oleracea thylakoids. These PET inhibitory active compounds also exhibited a strong and similar inhibition both against atrazine-resistant Chenopodium album thylakoids as well as against thylakoids from wild-type Chenopodium. The herbicidal activity of 4-(4-bromoben-zylamino)-2-methyl-6-trifluoromethylpyrimidine was equivalent to that of known herbicides like simetryne, simazine or atrazine.
