What is Synthesis and structure of {{amino(triorganosilyl)carbene}pentacarbonyltungsten(0)} complexes and attempted synthesis of {[2-bis(trimethylsilyl)methyl-3-triorganosilyl-2H-azaphosphirene-κP]pentacarbonyltungsten(0)} about?

## First examples of tungsten aminocarbene complexes [(OC were synthesized via ammonolysis of the corresponding methoxycarbene complexes 1aed. They were characterized by NMR spectroscopy, MS, IR, UV/Vis and elemental analysis, and in the case of the C-triphenylsilyl derivative 2a by single-crystal X-ray structure analysis. The reaction of P-chloro alkylidenephosphane 3 with complexes 2aed, meant to give 2H-azaphosphirene complexes, was monitored by 31 P NMR spectroscopy to reveal the formation of the products 4e7, which were presumably formed via decomposition of the transient complexes 10aed.
