temperature is not reported; however, doping of copper with molybdenum metal has been realized here to be more efficient for C-S cross-coupling in comparison to general CuII catalyst. The doped catalyst CuMoO4 nanoparticle is found to be more efficient than copper. The catalyst works under mild conditions without any ligand at room temperature and is recyclable and effective for a wide range of thiols and
disclosed new bimetallic BaMoO4 nanoparticles for the C–Scross-couplingreaction. The C–Scross-couplingreaction of alkyl/aryl thiols with haloarenes was accomplished with high yields. The reaction has good functional group tolerance and selectivity. This is an efficient protocol for synthesizing the building blocks of pharmaceuticals containing C–S bonds. The catalyst is recyclable. The unactivated

A sulfamoyltriazole derivative represented by general formula (I) and a bactericide containing the same as the active ingredient, wherein R¹ and R² may be the same or different from each other and each represents lower alkyl, or alternatively R¹ and R² may be combined together to represent C₃-C₆ alkylene which may be substituted by lower alkyl; A represents substituted aryl; and l represents an integer of 0 to 1. The bactericide has prophylactic and therapeutic effects against various disease damages even in an extremely low dose without inflicting any chemical injury to agrohorticultural crops.

The present invention relates to a sulfamoyl triazole derivative and a fungicide containing same as an effective component, the sulfamoyl triazole derivative being expressed by general formula (I): ##STR1## in which R.sup.1 and R.sup.2 are the same or different lower alkyl groups or an alkylene chain formed by integrating R.sup.1 and R.sup.2 and having 3 to 6 carbon atoms which may be substituted by a lower alkyl group; p is an integer 0 or 1; and A is a substituted aryl group. The fungicide does not damage field and garden plants and it is effective for preventing and curing various disease injury at very small dosages.
