Selenocarbonyl difluoride

CHjSe The preparation of stable aliphatic selones was first reported in 1976 by Bartow and coworkers They found it was possible to stabilize these molecules in the liquid phase by attaching bulky substituents such as the t-butyl group or ring structures directly to the selenocarbonyl function. Halogens are known to stabilize the thiocarbonyl group, and the same year Haas et al. reported the properties of monomeric selenocarbonyl difluoride, CF Se. Selenoacetaldehyde and selenoformaldehyde were detected in the gas phase somewhat later by the combined tech-... 

Selenocarbonyl halides Only two selenocarbonyl halides are known, CF Se and CCljSe. Selenocarbonyl difluoride is formed by the pyrolysis of B(SeCF3)j in the presence of KF. Chlorination with Cl gives the dichloride.
