Tetrel and pnictogen functionalised propargylidynes†
Abstract
The reaction of [W(CCCSiMe3)(CO)2(Tp*)] (Tp* = tris(dimethylpyrazolyl)borate) with AgNO3 affords {[W(CCCAg)-(CO)2(Tp*)][AgNO3]}n while [Hg{CCCW(CO)2(Tp*)}2] with nBuLi affords [W(CCCLi)(CO)2(Tp*)]. These anhydrous reagents allow the installation of main group elements (e.g., Si, Sn, Pb, P, As) as propargylidyne termini.
