Phosphonic acid mediated practical dehalogenation and benzylation with benzyl halides?
RSC Advances Pub Date: 2019-07-18 DOI: 10.1039/C9RA04770K
Abstract
For the first time, by using H3PO3/I2 system, various benzyl chlorides, bromides and iodides were dehalogenated successfully. In the presence of H3PO3, benzyl halides underwent electrophilic substitution reactions with electron-rich arenes, leading to a broad range of diarylmethanes in good yields. These transformations feature green, cheap reducing reagents and metal-free conditions. A possible mechanism was proposed.
