{"doi":"10.1002/anie.202316378","title":"Formation of a Reactive [Mn(III)−O−Ce(IV)] Species and its Facile Equilibrium with Related Mn(IV)(OX) (X = Sc or H) Complexes","abstract":"Abstract Lewis acid‐bound high valent Mn‐oxo species are of great importance due to their relevance to photosystem II. Here, we report the synthesis of a unique [(BnTPEN)Mn(III)−O−Ce(IV)(NO 3 ) 4 ] + adduct ( 2 ) by the reaction of (BnTPEN)Mn(II) ( 1 ) with 4 eq. ceric ammonium nitrate. 2 has been characterized using UV/Vis, NMR, resonance Raman spectroscopy, as well as by mass spectrometry. Treatment of 2 with Sc(III)(OTf) 3 results in the formation of (BnTPEN)Mn(IV)−O−Sc(III) ( 3 ), while HClO 4 addition to 2 forms (BnTPEN)Mn(IV)−OH ( 4 ), reverting to 2 upon Ce(III)(NO 3 ) 3 addition. 2 can also be prepared by the oxidation of 1 eq. Ce(III)(NO 3 ) 3 with [(BnTPEN)Mn(IV)=O] 2+ ( 5 ). In addition, the EPR spectroscopy revealed the elegant temperature‐dependent equilibria between 2 and Mn(IV) species. The binding of redox‐active Ce(IV) boosts electron transfer efficiency of 2 towards ferrocenes. Remarkably, the newly characterized Mn(III)−O−Ce(IV) species can carry out O‐atom and H‐atom transfer reactions.","journal":"Angewandte Chemie International Edition","year":2023,"id":350477,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":10,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9533,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1094853,"name":"Pragya Arora","orcid":null,"position":1,"is_corresponding":false},{"id":1094445,"name":"Rakesh Kumar","orcid":"0000-0003-1658-1738","position":2,"is_corresponding":false},{"id":1094446,"name":"Ayushi Awasthi","orcid":"0000-0002-5135-8366","position":3,"is_corresponding":false},{"id":1094447,"name":"Bittu Chandra","orcid":"0000-0001-6071-8071","position":4,"is_corresponding":false},{"id":1094448,"name":"Raju Eerlapally","orcid":"0000-0003-3720-9097","position":5,"is_corresponding":false},{"id":1061763,"name":"Jin Xiong","orcid":"0000-0001-7443-0554","position":6,"is_corresponding":false},{"id":777300,"name":"Yisong Guo","orcid":"0000-0002-4132-3565","position":7,"is_corresponding":false},{"id":514407,"name":"Lawrence Que","orcid":"0000-0002-0989-2813","position":8,"is_corresponding":false},{"id":514405,"name":"Apparao Draksharapu","orcid":"0000-0001-7897-3230","position":9,"is_corresponding":false},{"id":1094444,"name":"Sikha Gupta","orcid":"0000-0002-8804-3405","position":0,"is_corresponding":true}],"reference_count":44,"raw_metadata":null,"created_at":"2026-07-19T01:12:23.769679Z","pmid":"37997195","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
