Powder X\u2010ray diffraction, scanning electron microscopy, and energy\u2010dispersive X\u2010ray spectroscopy revealed that [P<jats:sub>66614<\/jats:sub>]Cl is the most promising candidate for the single phase synthesis of AuTe<jats:sub>2<\/jats:sub> at 200\u2009\u00b0C. Ag<jats:sub>2<\/jats:sub>Te was obtained using the same ILs by reducing the temperature in the flask to 60\u2009\u00b0C. Even at room temperature, quantitative yield was achieved by using either 2\u2005mol\u2009% of [P<jats:sub>66614<\/jats:sub>]Cl in dichloromethane or a planetary ball mill. Diffusion experiments, <jats:sup>31<\/jats:sup>P and <jats:sup>125<\/jats:sup>Te\u2010NMR, and mass spectroscopy revealed one of the reaction mechanisms at 60\u2009\u00b0C. Catalytic amounts of alkylphosphanes in commercial [P<jats:sub>66614<\/jats:sub>]Cl activate tellurium and form soluble phosphane tellurides, which react on the metal surface to solid telluride and the initial phosphane. In addition, a convenient method for the purification of [P<jats:sub>66614<\/jats:sub>]Cl was developed.<\/jats:p>","DOI":"10.1002\/open.202000249","type":"journal-article","created":{"date-parts":[[2020,10,19]],"date-time":"2020-10-19T14:05:33Z","timestamp":1603116333000},"page":"117-124","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Low Temperature Activation of Tellurium and Resource\u2010Efficient Synthesis of AuTe<sub>2<\/sub> and Ag<sub>2<\/sub>Te in Ionic Liquids"],"prefix":"10.1002","volume":"10","author":[{"given":"Matthias A.","family":"Grasser","sequence":"first","affiliation":[{"name":"Faculty of Chemistry and Food Chemistry Technische Universit\u00e4t Dresden  01062 Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Pietsch","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Food Chemistry Technische Universit\u00e4t Dresden  01062 Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3511-9899","authenticated-orcid":false,"given":"Eike","family":"Brunner","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Food Chemistry Technische Universit\u00e4t Dresden  01062 Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7523-9313","authenticated-orcid":false,"given":"Thomas","family":"Doert","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Food Chemistry Technische Universit\u00e4t Dresden  01062 Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2391-6025","authenticated-orcid":false,"given":"Michael","family":"Ruck","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Food Chemistry Technische Universit\u00e4t Dresden  01062 Dresden Germany"},{"name":"Max-Planck-Institut f\u00fcr Chemische Physik fester Stoffe  N\u00f6thnitzer Str. 40 01187 Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,10,19]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1039\/c2nr30469d"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apsusc.2017.08.053"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6TC02501C"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jallcom.2010.02.030"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1557\/jmr.2013.196"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/jp804053c"},{"key":"e_1_2_7_7_1","first-page":"15","volume":"106","author":"Zhang W.","year":"2011","journal-title":"Phys.
