Chemists Ante Up On Phospholes
Phosphorus-containing heterocyclic compounds, known as phospholes, are frequently used in organic electronics, as bioimaging probes, and in catalysts. Three research groups are now reporting new ways to make the molecules. In one case, François Mathey of Nanyang Technological University and Zheng Duan of Zhengzhou University and coworkers have created an atom-efficient Pd/Cu-catalyzed ring-closing reaction of alkyne-substituted phenylphosphines to produce benzophospholes (Org. Lett. 2015, DOI: 10.1021/acs.orglett.5b02926). In another case, a team . . .
