Surprisingly low thermal stability in solution is displayed by the 2 H ‐1,2‐azaphosphirene tungsten complex 1 ; acetylene derivatives and benzaldehyde were used to trap an intermediate phosphanediyl tungsten complex formed from 1 . The reaction of 1 with benzaldehyde provides a new, diastereoselective route to oxaphosphirane tungsten complexes.
