The present invention relates to the use of a compound containing a moiety of formula (I) as a reagent for linking a compound of formula R1—H which comprises a first functional moiety of formula F1 to a second functional moiety of formula F2
wherein X, X′, Y, R1, F1 and F2 are as defined herein. The present invention also provides related processes and products. The present invention is useful for creating functional conjugate compounds, and specifically conjugates in which at least one of the constituent molecules carries a thiol group.

Bromomaleimides are useful building blocks in synthesis and powerful reagents for the selective chemical modification of proteins. A mild new synthesis of these reagents is described, along with the convenient transferability of the approach to dithiomaleimides and bromopyridazinediones. (c) 2013 The Authors.

Reversibleprotein biotinylation is readily affected via conjugation with a bromomaleimide-based reagent followed by reductive cleavage. The intermediate biotinylated protein constructs are stable at physiological temperature and pH 8.0. Quantitative reversibility is elegantly delivered undermildconditions of using a stoichiometric amount of a bis-thiol, thus providing an approach that will be of
