Abstract

The addition of allyl chloride or cinnamyl chloride to a (highly colored) solution of 2a–d in acetonitrile resulted in a pale-brown solution within 1h. When the reaction was performed in the presence of KPF6, subsequent workup afforded pale-yellow crystals of 3d or orange– yellow crystals of 4a–d, in 71–88% yield (Scheme 1). Complexes 2–4 are stable in air at the solid state and were characterized by 1H and 13C {1H} NMR spectroscopy and ...
