✦ Synopsis

The reaction of tert-butylalkynyl chromium Fischer carbene complex 1 with nitrones 2 affords β-enamino-ketoaldehydes 4 by the light-promoted rearrangement of the corresponding [3+2] cycloadduct carbene complexes 3. On the other hand,

The chemistry of stabilized Group 6 metal carbene complexes (Fischer carbenes) has reached a high level of maturity and carbenes have become very valuable building blocks in organic synthesis. In spite of this, the reactivity of highly reduced Fischer carbene complexes has been somewhat neglected.
