Nitrosation with complex NOCl center dot 2SO(3) of gem-dichloroarylcyclopropanes containing acceptor substituents in the aromatic ring proceeded chemo- and regioselectively affording 3-aryl-5-chloroisoxazoles in high yields. The presence of donor substituents complicated the reaction by the occurrence of competing processes.
