Question

A recent article reported that benzylic bromination can be achieved photochemically using bromotrichloromethane as the brominating agent (you used NBS in lab) as shown below. Draw the mechanism of this reaction, labeling all sets as either "Initiation" or "Propagation". Also, show one feasible termination step. Helpful BDE's are given. How many unique hydrogens (NMR) are present in the product? Br BrCCI3 Org. Biomol. Chem. 2019, 17, 1384. hy Me0 OME OME Me01 ОMe ОMe BDE of C-Br bond -230 kJ/mol BDE of C-H in HCC13 - 401 kJ/mol
