Careful pyrolysis of a solid [Co(acac)2]\/phthalocyanine\/Vulcan mixture (acac = acetylacetonate) under an argon atmosphere furnishes a ready-to-use, catalytically active material that can be handled without any protection from air. The composite so obtained was then used in the pressure hydrogenation of azo dyes (60 \u00b0C, 50 bar H2) to yield the corresponding aniline derivatives, without any additive. The potential of the catalyst to design a bootstrap synthesis approach of aromatic amines, i.e., their generation from within themselves, by way of reduction of symmetric azo compounds is explored herein, too. To further demonstrate the practicality of the introduced catalyst, we also applied it to the hydrogenation of nitroarenes as another means for the production of arylamines. In all investigated cases, the NO2 motif was neatly and selectively converted into the desired NH2 group under very mild reaction conditions (room temperature, 20 bar H2) and, again, without the need for any auxiliary reagents.<\/jats:p>","DOI":"10.1021\/acsomega.6c03689","type":"journal-article","created":{"date-parts":[[2026,8,5]],"date-time":"2026-08-05T13:02:52Z","timestamp":1785934972000},"page":"47904-47912","source":"Crossref","is-referenced-by-count":0,"title":["Bootstrap Synthesis\nRevisited: A Solid, Cobalt-Derived\nCatalyst Enables the Hydrogenation of N\u2550N Bonds to Afford Anilines"],"prefix":"10.1021","volume":"11","author":[{"given":"Fabian","family":"Schmiedbauer","sequence":"first","affiliation":[{"name":"Johannes Kepler University (JKU) , , ,","place":["Linz, Austria, 4040"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiri","family":"Duchoslav","sequence":"additional","affiliation":[{"name":"Johannes Kepler University (JKU) , , ,","place":["Linz, Austria, 4040"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Zellner","sequence":"additional","affiliation":[{"name":"Johannes Kepler University (JKU) , , ,","place":["Linz, Austria, 4040"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7595-3074","authenticated-orcid":true,"given":"Christoph","family":"Topf","sequence":"additional","affiliation":[{"name":"Johannes Kepler University (JKU) , , ,","place":["Linz, Austria, 4040"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,4]]},"reference":[{"issue":"2","key":"2026081811105949000_cit1","doi-asserted-by":"publisher","first-page":"210","DOI":"10.1002\/cctc.200900129","article-title":"Selective Catalytic Hydrogenation\nof Functionalized Nitroarenes: An update","volume":"1","author":"Blaser","year":"2009","journal-title":"ChemCatChem"},{"issue":"4","key":"2026081811105949000_cit2","doi-asserted-by":"publisher","first-page":"430","DOI":"10.1021\/acs.oprd.6b00205","article-title":"Recent Developments\nin the Reduction of Aromatic and Aliphatic Nitro Compounds to Amines","volume":"22","author":"Orlandi","year":"2018","journal-title":"Org.
