Abstract
Unexpected reaction pathways and products are apparently not the exception for reactions of Fischer carbenes, and full recognition of the whole potential of this type of complex in organic synthesis is still long way off. Among the classic synthetic applications is the Dötz reaction. One of the many new transformations is the successive reaction of complexes 1 with HNMe2 and pent-1-yne to give cyclopenta[b]pyran 2 and the fulvene complex 3.
