Oxidation and Selenization Reactions of a Kinetically Stabilized 1,2-Bisferrocenyldisilene

Abstract

The reaction of the first stable (E)-1,2-bisferrocenyldisilene, Tip(Fc)Si˭Si(Fc)Tip (Tip = 2,4,6-triisopropylphenyl, Fc = ferrocenyl), with aerobic oxygen afforded the corresponding trans-1,3,2,4-dioxadisiletane exclusively, while the reaction of Tip(Fc)Si˭Si(Fc)Tip with an excess amount of elemental selenium gave the corresponding trans-selenadisilirane in high yield. The structural parameters of the isolated trans-1,3,2,4-dioxadisiletane and trans-selenadisilirane were revealed by X-ray crystallographic analysis, and the results were compared with those of related compounds.
