TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): 6 Methods for preparation of the triazole compound are given e.g. (epoxidation reaction) reacting cyclopentanone compound of formula (XI) with trimethylsulfonium salt such as trimethylsulfonium bromide in presence of metal oxide e.g. sodium oxide and optionally a base e.g. sodium hydride in a two-phase solid/liquid system comprising an organic solvent, e.g. toluene to obtain oxirane compound of formula (XII); reacting oxirane compound (XII) with (1,2,4)-1H-triazole in the presence of a base e.g. sodium hydride in a solvent e.g. toluene to obtain triazole compound (XIII); and sulfurizing the compound (XIII) to obtain triazole compound (IA) (where R4 is H, n is 0 and b is single bond). Preferred Definitions:    b=single bond;    L'= 2-3C alkyl, 2-3C alkoxy, 2,2,2-trifluoroethyl, 1,1,2,2-tetrafluoroethyl, penta-fluoroethyl, 2,2,2-trifluoroethoxy, 1,1,2,2-tetrafluoroethoxy or pentafluoroethoxy;    R1 and R2= methyl;    R3=H;    R5=1-4C alkyl, 1-4C alkoxy, phenyl, phenoxy or NR9R10;    R9=H;    R10=H, 1-4C alkyl or phenyl;    M1=Na+ or K+, one half Mg2+, one half Cu2+, one half Zn2+, one half Fe2+ or one half Ni2+ or ammonium cation of formula (NR1aR1bR1cR1d)+;    R1a-R1d=H, trimethylammonium or triethylammonium;    R4=H, CN or methyl;    R4a=H, 1-4C-alkyl or 1-4C haloalkyl;and    n=0.    One of R1a-R1d is H and three of R1a-R1d are trimethylammonium or triethylammonium.    ACTIVITY - Plant Protectant; Fungicide; Cytostatic; Virucide; Anti-HIV.
