Independent claims are also included for: (1) preparation of (I); and (2) dicarbonyl compound intermediates of formula (III), provided that n is not 0 and R1 and R2 are not both Me. [Image] - ACTIVITY : Fungicide. 7-Cyclohexyl-5-methyl-6-(2-chloro-6-fluorophenyl)-1,2,4-triazolo[1,5- a]pyrimidine (Ia) at a concentration of 63 ppm gave at least 90 % protection of tomato plants against Alternaria solani. - MECHANISM OF ACTION : None given.
