I found the field of Chemistry very interesting. Saw the article Pummerer Synthesis of Chromanes Reveals a Competition between Cyclization and Reductive Chlorination published in 2019. Quality Control of 3-(Trifluoromethyl)phenol, Reprint Addresses Gamba-Sanchez, D (corresponding author), Univ Andes, Dept Chem, Lab Organ Synth Bio & Organocatalysis, Cra 1 18A-12 Q 305, Bogota 111711, Colombia.. The CAS is 98-17-9. Through research, I have a further understanding and discovery of 3-(Trifluoromethyl)phenol
The competition between an unprecedented reductive chlorination and the Pummerer reaction was studied and applied to the synthesis of benzofused oxygen heterocycles including 3-aminochromanes and in the intramolecular chlorination of activated aromatic rings. The use of (COCl)(2) as a Pummerer activator showed substantial activity, producing alpha-chlorinated sulfides that can undergo Pummerer-Friedel-Crafts cyclization. If the aromatic ring has electron-donating groups in position three, then the reaction follows a different pathway, yielding the reductive chlorination products, where the chlorine atom comes from a sulfonium salt.
