to promote the thiocyanation of the C═Cbond in enaminones for the synthesis of α-thiocyanoketones and 2-aminothiazoles. The reactions of enaminones with ammonium thiocyanate provide α-thiocyanoketones with ultrasound irradiation at room temperature. More interestingly, simply further heating the vessel after ultrasonic irradiation leads to the selective synthesis of 2-aminothiazoles with an unconventional

Diaryl-azo derivatives are efficient fluorescence quenchers as well as nucleic acid duplex-stabilizing agents and are useful in oligonucleotide conjugates and probes. The oligonucleotide-quencher conjugates may be used in detection methods for nucleic acid targets.
