WebMay 28, 2024 · 2 Answers. Sorted by: 20. Part of the reason why there has been very little research done on organoastatine chemistry is the extreme radioactivity of astatine; the half-life of X 210 X 2 2 210 A t, the longest-lived isotope, is about 8 hours. However, the element can be incorporated into organic compounds (e.g., via a destannylation reaction). 1. WebOrganoastatine chemistry describes the synthesis and properties of chemical compounds containing a carbon to astatine chemical bond . Astatine is extremely radioactive, with the longest-lived isotope ( 210 At) having a half-life of only 8.1 hours. Consequently, organoastatine chemistry can only be studied by tracer techniques on extremely small ...
