Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Stoichiometric reduction of N₂ at a Mo center stabilized by a bulky tetradentate phosphine ligand (<inline-formula><alternatives><tex-math notation="tex"><![CDATA[${{\rm PP}{{{\rm Cy}\hfill \atop 3\hfill}}}$]]></tex-math><inline-graphic xlink:href="ark:/27927/pgh2qxfg753" mimetype="image" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></alternatives></inline-formula>) allowed isolation of Mo–imidoamine and Mo–imido complexes. Both complexes as well as the Mo^II precursor are equally suitable catalysts for the synthesis of NTMS₃ (TMS=trimethylsilyl) from N₂, TMSCl, and electron sources. Mechanistic studies prove the involvement of a TMS radical at least in one of the catalytic steps.</p> </abstract>
