Disclosed are novel conjugates and processes for the preparation thereof. A process for the preparation of alkene- or alkyne-phosohonothiolates and -phosphonates comprises the step of: reacting a compound of formula (I) with a thiol-containing molecule of formula (II) wherein represents an amino acid, a peptide, a protein, an antibody, a nucleotide, an oligonucleotide, a saccharide, a polysaccharide, a polymer, an optionally substituted C

on cysteine side chains within peptides and proteins. In addition to labeling the monoclonalantibody trastuzumab with excellent cysteine-selectivity, we applied our protocol for the site-specific conjugation of two proteins with unique cysteine residues yielding a non-hydrolyzable phosphonothiolate-linked diubiquitin and an ubiquitin-α-synuclein conjugate. The latter was recognized as a substrate in
