Remarkably stable —even with a hydrogen atom at the low‐coordinate phosphorus center! A straightforward synthesis provides the thermally robust phosphasilenes ( E )/( Z )‐ 1 , which have a terminal PH group. These compounds can be cleanly metalated with dimethylzinc in the presence of tmeda (tetramethylethylenediamine) to afford exclusively the P ‐zincio‐substituted phosphasilene 2 with E configuration. R=2,4,6‐triisopropylphenyl.
