Abstract Several new 1, 1'‐bis (sulfonyl) ferrocenes designed for the synthesis of
sulfonamide linked biological conjugates have been prepared. 1, 1'‐Bis (sulfonylbromide)
ferrocene can be produced from the corresponding sulfonylchloride via a bis
(sulfonylhydrazide) intermediate. Bis (sulfonyl‐N‐hydroxybenzotriazole) ferrocene can also
be synthesized from the sulfonyl chloride, and reaction of glycine methyl ester with the
sulfonyl chloride affords a [3] ferrocenophane complex. All new compounds have been …

Abstract
Several new 1,1’‐bis(sulfonyl)ferrocenes designed for the synthesis of sulfonamide linked biological conjugates have been prepared. 1,1’‐Bis(sulfonylbromide)ferrocene can be produced from the corresponding sulfonylchloride via a bis(sulfonylhydrazide) intermediate. Bis(sulfonyl‐N‐hydroxybenzotriazole)ferrocene can also be synthesized from the sulfonyl chloride, and reaction of glycine methyl ester with the sulfonyl chloride affords a [3]ferrocenophane complex. All new compounds have been structurally characterized by X‐ray crystallography.
