A compound of formula (I) as described herein and methods and uses thereof as probes in the mass tagging of biosensors or biologically active materials for use in mass cytometry analysis of tissue samples such as in the detection, labelling and quantification of oxygen-deprived cells by using, for example, tellurophene-tagged 2-nitroimidazole.
Sodium hydrogen telluride opens many epoxides cleanly by an SN2 process to give telluro-alcohols, which by reduction with nickel boride afford alcohols. An intermediate telluro-alcohol was converted to olefin in high yield by treatment with -toluene-sulphonyl chloride in pyridine. Quaternary ammonium salt are also cleaved efficiently by sodium hydrogen telluride.
