The effect of the geometric constraint on the electronic structure was probed by theoretical calculations and derivatization reactions. Reactions with N\u2212H bonds result in formation of cooperative addition products. The thermochemistry of these transformations is strongly dependent on the substrate, with ammonia activation being thermoneutral. This represents the first example of a molecular compound that reversibly activates ammonia via N\u2212H bond scission in solution upon mild heating.<\/jats:p>","DOI":"10.1002\/anie.202111017","type":"journal-article","created":{"date-parts":[[2021,9,3]],"date-time":"2021-09-03T10:48:42Z","timestamp":1630666122000},"page":"23625-23629","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Thermoneutral N\u2212H Bond Activation of Ammonia by a Geometrically Constrained Phosphine"],"prefix":"10.1002","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8787-6253","authenticated-orcid":false,"given":"Josh","family":"Abbenseth","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Oxford  12 Mansfield Road OX1 3TA Oxford UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9556-6450","authenticated-orcid":false,"given":"Oliver P.
