Beta-picoline derivs. (I) and their N-oxides and addn. salts are new. In (I), A = CR1R2; R1, R2 = H, 1-6C alkyl, 2-6C alkenyl or 2-6C alkynyl; or R1+R2 = 2-6C n-alkylene; B = CH2, CHOR3, CHR4 or C=NOR5; R3 = H, 1-6C alkyl, 1-6C haloalkyl, 3-8C cycloalkyl, 3-6C alkenyl, 2-6C acyl or phenyl, benzyl or benzoyl opt. mono-, di- or tri-substd. in the ring by 1-4C alkyl, 1-4C alkoxy, 1-4C haloalkyl, 1-4C haloalkoxy, halogen, cyano or nitro; R4 = H, F, Cl, Br or I; R5 = H, 1-6C alkyl, 1-6C haloalkyl, 3-7C cycloalkyl, 3-6C alkenyl or aryl-1-4C alkyl opt. mono-, di- or tri-substd. in the aryl ring by 1-4C alkyl, 1-4C alkoxy, 1-4C haloalkyl, halogen, cyano or nitro; Ar = phenyl or naphthyl opt. mono-, di- or tri-substd. by halogen, 1-6C alkyl, 1-4C alkoxy, 1-4C haloalkyl, 1-4C haloalkoxy, phenyl, phenoxy, halophenyl, halophenoxy or benzyloxy; except 1-phenyl-3-(3-pyridyl) propan-1-one (IA). The use of cpd. (IA), which is known from J. Org. Chem. 43 (1978), 3396 and Arch. Pharm. 307 (1974), 550, for the control of fungi is also claimed. Further, intermediates (II) are claimed except where A = CH2 or CH(CH3). 3 Cpds. (I), e.g., 2-ethyl-1-(4-fluorophenyl) -2-(pyridyl-3-methyl)butan-1-ol, are specifically claimed. |
