SUMMARY

The discussion centers on the tautomerization mechanism in silver cyanide (AgCN) and silver isocyanide (AgNC), clarifying that the process is more accurately described as isomerization rather than tautomerization. Participants highlight that tautomerization involves a dynamic equilibrium between constitutional isomers, as defined by the IUPAC Gold Book. The conversation also touches on potassium cyanide (KCN) and potassium isocyanide (KNC), emphasizing the excitation of bending modes as a contributing factor to the isomerization process.

PREREQUISITES
  • Understanding of tautomerization and isomerization concepts
  • Familiarity with IUPAC nomenclature and definitions
  • Knowledge of molecular vibrations and bending modes
  • Basic chemistry of cyanides and isocyanides
NEXT STEPS
  • Research the differences between tautomerization and isomerization in organic chemistry
  • Study the IUPAC Gold Book for detailed definitions and examples
  • Explore molecular vibration theories, focusing on bending modes
  • Investigate the properties and reactions of KCN and KNC
USEFUL FOR

Chemists, particularly those specializing in organic chemistry and coordination compounds, as well as students seeking to deepen their understanding of isomerization mechanisms.

Can anyone give a detailed mechanism for the tautomerization in AgCN and AgNC and is the same possible in KCN and KNC ??

I don't know what you mean by "detailed mechanism" here, but I can't tell you that this is not a tautomerization, simply an isomerization.
 
Dynamic equilibrium existing between two constitutional isomers is TAUTOMERIZATION( a specific type of isomerization), right, that's what is happening here, but can a mechanism be presented??
 
Apologies, I was wrong. I thought that tautomerization only applied when H was being exchanged, but looking in the IUPAC Gold Book, it is more general than that. That said, I always heard it referred to as isomerization in the case of KCN, and even HCN with which I am more familiar.

Apart from writing KCN##\rightleftharpoons##KNC, I don't know of anything more complicated. I always understood it as being due to the excitation of the bending mode.
