In this reaction, two equivalents nitrene are used to functionalize a C-C triple bond by gold catalysis. Subsequently one equivalent nitrene remains in the amide function of the desired product, while the other equivalent of nitrene is eliminated during the hydrolysis process as an amine. This particular hydrolysis of the intermediate α-iminoimidoyl halides opens access to α-ketoamides for a wide range of haloalkynes. In Chapter 3, a one-step gold-catalyzed hydroamination of alkynes with hydroxylamine-O-sulfonic acid (HOSA) is reported. In this reaction, the limits that traditional synthesis of oximes is highly dependent on carbonyl compounds, is overcome, which expands the diversity of accessible oximes. Green chemistry metrics for this facile reaction are also calculated, this process shows 100% carbon efficiency. date: 2023 id_scheme: DOI id_number: 10.11588/heidok.00032578 ppn_swb: 1871466806 own_urn: urn:nbn:de:bsz:16-heidok-325781 date_accepted: 2022-12-14 advisor: HASH(0x561a62ace348) language: eng bibsort: WUZUOZUOFUNCTIONAL20221222 full_text_status: public place_of_pub: Heidelberg citation: Wu, Zuozuo (2023) Functionalized Molecular Diversity by Gold-Catalyzed Activation of Alkynes.
