Compound <jats:bold>2<\/jats:bold> is a rare example of a phosphadiazadiene ligand (R\u2010P=N\u2212N=CR\u2032R\u2032\u2032) complex. At temperatures above 0\u2009\u00b0C, <jats:bold>2<\/jats:bold> decomposes into the complex [{W(CO)<jats:sub>5<\/jats:sub>}PCp*{N(H)N=CPh<jats:sub>2<\/jats:sub>)<jats:sub>2<\/jats:sub>] (<jats:bold>3<\/jats:bold>), among other species. The reaction of the pentelidene complexes [Cp*E{W(CO)<jats:sub>5<\/jats:sub>}<jats:sub>2<\/jats:sub>] (E=P, As) with diazomethane (CH<jats:sub>2<\/jats:sub>NN) proceeds differently.

The reaction with the phosphinidene complex (<jats:bold>1\u2009a<\/jats:bold>) results in three products, the two phosphaalkene complexes [{W(CO)<jats:sub>5<\/jats:sub>}<jats:sub>2<\/jats:sub>{\u03b7<jats:sup>1:2<\/jats:sup>\u2010(R)P=CH<jats:sub>2<\/jats:sub>}] (<jats:bold>4\u2009a<\/jats:bold>: R=Cp*, <jats:bold>5<\/jats:bold>: R=H) and the triazaphosphole derivative [{W(CO)<jats:sub>5<\/jats:sub>}P(Cp*)\u2010CH<jats:sub>2<\/jats:sub>\u2010N{W(CO)<jats:sub>5<\/jats:sub>}=N\u2010N(N=CH<jats:sub>2<\/jats:sub>)] (<jats:bold>6\u2009a<\/jats:bold>). The phosphaalkene complex (<jats:bold>4\u2009a<\/jats:bold>) and the arsaalkene complex (<jats:bold>4\u2009b<\/jats:bold>) are not stable at room temperature and decompose to the complexes [{W(CO)<jats:sub>5<\/jats:sub>}<jats:sub>4<\/jats:sub>(CH<jats:sub>2<\/jats:sub>=E\u2212E=CH<jats:sub>2<\/jats:sub>)] (<jats:bold>7\u2009a<\/jats:bold>: E=P, <jats:bold>7\u2009b<\/jats:bold>: E=As), which are the first examples of complexes with parent 2,3\u2010diphospha\u20101,3\u2010butadiene and 2,3\u2010diarsa\u20101,3\u2010butadiene ligands.<\/jats:p>","DOI":"10.1002\/anie.201607793","type":"journal-article","created":{"date-parts":[[2016,10,12]],"date-time":"2016-10-12T22:04:19Z","timestamp":1476309859000},"page":"14037-14040","source":"Crossref","is-referenced-by-count":20,"title":["Reaction of Pentelidene Complexes with Diazoalkanes: Stabilization of Parent 2,3\u2010Dipnictabutadienes"],"prefix":"10.1002","volume":"55","author":[{"given":"Michael","family":"Seidl","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Anorganische Chemie der Universit\u00e4t Regensburg  93040 Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Stubenhofer","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Anorganische Chemie der Universit\u00e4t Regensburg  93040 Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexey Y.","family":"Timoshkin","sequence":"additional","affiliation":[{"name":"Institute of Chemistry St. Petersburg State University  198504 Old Peterhof St. Petersburg Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2182-5020","authenticated-orcid":false,"given":"Manfred","family":"Scheer","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Anorganische Chemie der Universit\u00e4t Regensburg  93040 Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,10,6]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1039\/CT8864900074"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/cber.19831160311"},{"key":"e_1_2_2_3_1","unstructured":"\u00a0"},{"key":"e_1_2_2_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/cber.19851180407"},{"key":"e_1_2_2_5_2","first-page":"2140","volume":"55","author":"Romanenko V.
