Addition compounds between carbones, CL2, and main group Lewis acids: A new glance at old and new compounds

- The term “carbones” for compounds with a C(0) atom stabilized by neutral donors is elucidated.
- The electronic situation of carbones as σ and π donors is discussed.
- Main group Lewis acids A as acceptors cover electron deficient species from group 2 and groups 13-17 elements.
- Main group addition compounds of a series of different carbones are reviewed.
- Carbones comprise mainly carbodiphosphoranes, carbodicarbenes, and tetraaminoallene.
