5-η2-Os(II)pentaammine-3-vinylpyrrole complexes are synthesized from the corresponding 1-methylpyrrole complex by an electrophilic addition at the β-carbon, C(3), of the pyrrole ring. Four independent synthetic routes to β-vinylpyrrole complexes are described, each introducing different functionality on the pendant double bond. The uncoordinated portion of these complexeschemically and structurally resembles
