Abstract

The reactivity of various phosphaalkynes versus [W(CO)5thf] has been studied. The reaction with Mes*CP (Mes* = 2,4,6-tBu3C6H2) exclusively leads to the low yield formation of [W(CO)2{(2-PCMes*)W(CO)5}2] (1). The reaction of the less bulky tBuCP with [W(CO)5thf] results in high yields in [W(CO)2{4-(tBuC)2P2W(CO)5}{2-(tBuCP)W(CO)5}] (2) which possesses a 1,3-diphosphete ligand as well as a side-on ...
