“…Infrared spectra of solid Fe(IV)-oxo samples generated using 18 Olabeled water show expected peak shifts in the Fe−O vibrations, in agreement with a harmonic oscillator model (Table 3, Figure 5). Across this homologous series, the Fe−O bond for the 3-CF 3 derivative is the strongest among the three derivatives.…”

“…Across this homologous series, the Fe−O bond for the 3-CF 3 derivative is the strongest among the three derivatives. In addition, the 18 O-labeled [Fe IV (O)(PY5Me 2 -X)] 2+ species generated was subjected to mass spectrometric analysis. As the oxygen in the ferryl moiety is susceptible to facile exchange with oxygen from trace H 2 16 intermediates, where X = CF 3 , H, and Me, were detected directly (Table S3, Supporting Information).…”

“…Os tempos reacionais ficaram entre 6 e 72 h, à temperatura de 135 °C, com os rendimentos variando entre 29 e 82% (Esquema 9). Os autores argumentaram, após experimentos com a N,N-dimetil benzilamina (i.e., sem a carbonila para a complexação) e a N-metild 3 -pirrolidona, que a etapa-chave era a formação do intermediário cíclico com ligação C-Ir formada através de uma ativação C-H em carbono sp 3 .…”

“…Depois desta prova de conceito, os autores tentaram estender a metodologia para a ativação de ligações C(sp 3 58 relataram a olefinação enantiosseletiva de anéis aromáticos, usando como substratos sais de ácidos diaril acéticos. Novamente, as seletividades voltaram a ficar entre boas e excelentes e bons rendimentos foram obtidos (Esquema 15 C), em condições semelhantes às do trabalho anterior.…”
