H2-free route to actinide hydrides

Aurora Walshe writes about a hot ChemComm article for Chemistry World

Scientists in the US have shown that phenylsilane is a safer and more convenient replacement for hydrogen gas when synthesising uranium and thorium hydrides.

Thorium and uranium are the most abundant actinoid elements. Although many stable thorium and uranium oxides and minerals are found in nature, the other actinoids are almost exclusively found in nuclear waste. Understanding actinoid chemistry has important practical applications in the nuclear industry but it is also fundamentally fascinating as the actinoid f electrons are so unlike those of the lanthanoids. Scientists need to make and study actinoid complexes with different oxidation states and with different ligands to understand their chemistry. Unfortunately, organometallic actinide chemistry can be quite challenging as organoactinide complexes will react – sometimes violently – with air or water, meaning that specialist equipment is needed to make and store them safely.
