The use of cobalt-rhodium (Co2Rh2) heterobimetallic nanoparticles in the cyclohydrocarbonylation of substituted alkynes and tandem cyclohydrocarbonylation-CO insertion of α-keto alkynes to give 2(3H)- or 2(5/7)-furanones is described

Upon heating 3-aryl-5-phenyl-2(3H)-furanones (1a-C) with benzylamine at 100°C in the absence of solvents, ring opening occurred with the formation of the corresponding N-benzylamides (3a-c). When the latter compounds (3a-c) were allowed to react with thionyl chloride at room temperature, lhe corresponding isothiazolones (4a-c) were obtained. Treatment of the isothiazolones (4a-c) with sodium hydroxide in benzene at room temperature affected debenzoylation to give the corresponding 2-benzyl-4-aryl-3(2H)-isothiazolones (5a-c).
