L3 metal carbenes introductions

Types of M=C and M≡C Complexes

Do isolated stable carbenes exist

Yes, although they are uncommon, carbons with lone pairs do exist

Fischer carbene complexes

Fischer carbene reactivity

Fischer carbene complexes use as carbene transfer agents

Schrock alkylidenes overview

Schrock alkylidene reactivity - similarity to phosphorus ylides

Schrock alkylidene reactivity - reactions with alkenes and olefin metathesis

N-heterocylic carbene metal complexes

N-heterocyclic carbenes bonding compared to Fischer carbenes

Synthesis of NHC-metal complexes

Summary of M-C carbene properties

Spectroscopic characterisation of carbenes - can NMR distinguish them

NMR can suggest their presence but not always tell the types apart.
