Vilsmeier-Haack complex formation by Fe3O4@SiO2@CS@POCl2-x/DMF: an efficient catalyst for conversion of epoxides to β-bromoformates
{{output}}
The in situ generation of the Vilsmeier-Haack complex was studied by combining Fe3O4@SiO2@CS@POCl2-x with N,N-dimethylformamide (DMF), demonstrating remarkable efficiency and regioselectivity in transforming epoxides into β-bromoformates. The reported yields ... ...
