  with aroyl chlorides, catalysed by palladium(II) acetate, leads to styrene and stilbene derivatives. By appropriate choice of reaction conditions, particularly the ethylene pressure, the reaction can be made to produce either styrene or stilbene derivatives selectively. The reaction tolerates those common substituents which do not react with aroyl chlorides. Only trans-stilbene derivatives are formed

  Catalysis mediated by iron complexes is emerging as an eco-friendly and inexpensive option in comparison to traditional metal catalysis. The epoxidation of alkenes constitutes an attractive application of iron(III) catalysis, in which terminal olefins are challenging substrates. Herein, we describe our study on the design of biomimetic non-heme ligands for the in situ generation of iron(III) complexes

  Direct visible-light-mediated aminofluorination of styrenes has been developed with high regioselectivity. Shelf-stable N-Ts-protected 1-aminopyridine salt was used as the nitrogen-radical precursor, and the commercially available hydrogen fluoride-pyridine was used as the nucleophilic fluoride source. The synthesis of an analogue of LY503430 was performed to demonstrate the synthetic value of this
