Reaction with Nitrogen and Phosphorus Nucleophiles

Reaction of (l-alkynyl)carbene complexes with nitrogen- or phosphorus-containing compounds makes available a large variety of products. Among these are (enamino)carbene and ( enphosphino )carbene complexes, both of which have been widely used for the generation of organic products. 

4-Amino-1-chroma-1,3-dienes, 2-Amino-1-metalla-1-en-3-ynes, and 4-Amino-1-metalla-1,2,3-butatrienes by Aminolysis 

4-Amino-l-chroma-l,2,3-butatrienes 99 are most conveniently distinguished from the corresponding 2-amino-l-chroma-l-buten-3-ynes 98. The former compounds exhibit a strong [p(C = C=C)] band at 1974-1988 cm 1
