- large scale, in the context of green sustainable chemistry. For example, it has low atom economy due to its requirement of one molar equivalent of a phosphine reagent, and the formation of a corresponding amount of a phosphine oxide, usually Ph3P=O (2). There is also the associated problem of separating
Regiocontroled Pd-catalysed C5-arylation of 3-substituted thiophene derivatives using a bromo-substituent as blocking group
Beilstein J. Org. Chem. 2016, 12, 2197–2203, doi:10.3762/bjoc.12.210
