Iron(Ii) Metal-Ligand Cooperative Catalysts For Endo-Selective Intramolecular Hydrofunctionalization, Benjamin Bridge

Electronic Thesis and Dissertation Repository

Two new cationic Fe(II) P^R₂N^R'₂ complexes, [Fe(Cp*)(P^R₂N^Ph₂)(MeCN)]PF₆ (R = cyclohexyl, 3a) and [Fe(Cp*)(P^R₂N^Ph₂)(MeCN)]PF₆ (R = phenyl, 3b), were synthesized and characterized. The catalytic activity for intramolecular hydrofunctionalization was tested using the benchmark substrate 2-ethynylaniline (EA) and both catalysts effectively produced indole (Ind). The selectivity of catalysis was also tested using 2-ethynylbenzyl alcohol (EBA) and both catalysts formed only the endo product isochromene (IC). These complexes represent the first well-defined Fe(II) catalysts that …
