Summary
Silica gel packings containing copper salt bonded to cyano functional groups on the surface of silica particles were synthesized. It was found that such packings are capable of specific interactions with olefins. The interactions were diversified enough to allow the separation of geometrical isomers. Moreover, it was found that, because of the character of the cyano group, the differences between the packing with free −CN groups and the packing containing −CN groups bonded into a complex with Cu(II) were less marked than in the case of diphenylphosphine and thiol groups investigated earlier.
