Preparation and Reactions of Aliphatic 2‐Pentafluorosulfanyl Aldehydes

A facile preparation of aliphatic 2-pentafluorosulfanyl aldehydes is described. To investigate the utility of the aldehydes as synthetic building blocks, various transformations of the aldehydes were explored. The pentafluorosulfanyl group was stable under a variety of reaction conditions, and the pentafluorosulfanylated products were obtained in moderate to good yields in most cases.
