Abstract

The reaction of [W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CSiMe3)(CO)2(Tp*)] (Tp* = tris(dimethylpyrazolyl)borate) with AgNO3 affords {[W([triple bond, length as m-dash]CC[triple bond, length as m-dash]CAg)-(CO)2(Tp*)][AgNO3]}n while [Hg{C[triple bond, length as m-dash]CC[triple bond, length as m-dash]W(CO)2(Tp*)}2] with nBuLi 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.
