On the Knowledge of the “Silanephosphimine” (Phosphasilaethene) t Bu 2 Si = PSi t Bu 3 1,2) The lithium phosphide 3 acts as a source for the “silanephosphimine” 2 . Thermolysis of 3 at 80–120°C in the presence of Li ⊕ ( t Bu 3 Si ⊖ PH), CH 2 = CMe 2 , or CH 2 = CHCH = CH 2 leads to products 4, 7 or 8 , whose formation is interpretable by the reaction of the reactants with intermediately formed 2 .
