A novel type of silicon-containing alkynone reagents that target free thiols to produce the stable vinyl-sulfide linker under biocompatible conditions is reported. Besides simple aliphatic and aromatic thiols, this approach is also applicable to the labeling of thiols present in proteins, sugars and pharmaceuticals with full retention of silicon handles in most cases.
