The outside front cover of this week’s OBC is a communication from Barbara Zajcand colleagues at The City College and The City University of New York presenting a mild and efficient synthesis of 1-aryl-1-fluoroethenes from benzothiazolyl (aryl)fluoromethyl sulfones and paraformaldehyde, under DBU- or Cs2CO3-mediated conditions at room temperature.

The inside front cover is work from Keisuke Kato et al. at Toho University on the cyclization–carbonylation–cyclization coupling reaction of γ-propynyl-1,3-diketones catalysed by palladium(II)-bisoxazoline complexes to give symmetrical ketones bearing two oxabicyclic groups in moderate to excellent yields.
