Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

Angewandte Chemie, EarlyView.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

Azide‐to‐Diazo Transformation Facilitated by Michael Addition via Phosphazide Formation

Angewandte Chemie, EarlyView.
A new type of Michael addition based on azide‐to‐diazo conversion is disclosed. This unusual transformation proceeds via 1,4‐addition accompanied by N─N bond cleavage of phosphazide intermediates under practical conditions. The high versatility of the resulting Michael adducts enables the synthesis of a wide variety of organonitrogen compounds ...
