The reaction of [W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CSiMe 3 )(CO) 2 (Tp*)] (Tp* = tris(dimethylpyrazolyl)borate) with AgNO 3 affords {[W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CAg)-(CO) 2 (Tp*)][AgNO 3 ]} n while [Hg{C[triple bond, length as m-dash]CC[triple bond, length as m-dash]W(CO) 2 (Tp*)} 2 ] with n BuLi affords [W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CLi)(CO) 2 (Tp*)]. These anhydrous reagents allow the installation of main group elements (e.g., Si, Sn, Pb, P, As) as propargylidyne termini.
