Rearrangement Reactions Caused by Addition

Reaction (5.93) involves decomposition of the ligand which is bonded to the metal through nitrogen to give ammonium salt. 

Pentacarbonyl(methoxymethylcarbene)chromium, (OC)5CrC(OMe)Me, reacts with cyclohexylisocyanide to form the aziridine complex which, when reacting with methanol, affords a carbene complex with the opening of the three-member ring. 

Fischer-type complexes react with ynamines to give carbene compounds, which formally are products of the carbene ligand migration this process probably begins with nucleophilic attack of the ynamine on C arb- 

This reaction is stereospecific the vinylcarbene complex possessing E conflguration is formed in which the R and R are trans with respect to each other. 

insertion reaction product is formed when diphenylacetylene reacts with [TacpCl2(CHMe3)]
