DOI: 10.1021/acs.jpcc.9b09713
Abstract: Intramolecular dehalogenation reaction as an essential step is generally involved in the deprotection of carbon-carbon double bonds in solution chemistry. However, harsh reaction conditions often limit the functional-group compatibility and cause the selectivity problems. In… read more here.
