This account describes our work on the use of ambiphilic molecules as catalysts for the reduction of carbon dioxide. Starting with the discovery that aluminum ambiphilic species (Me 2 PCH 2 AlMe 2 ) 2 ( 1 ) and Al(C 6 H 4 -PPh 2 ) 3 ( 5 ) could coord

The cleavage of a Csp3 -H bond by an N/B frustrated Lewis pair (FLP) is reported. Upon mild heating, the ambiphilic molecule (2-NMe2 -C6 H4 )2 BH activates the C-H bond of a methyl group in α position of a nitrogen atom to generate an unprecedented

Toward the preparation of a coordination complex of the heterodiatomic molecule PN, P≡N-V(N[tBu]Ar)3 (1, Ar = 3,5-Me2C6H3), we report the use of ClPA (A = C14H10, anthracene) as a formal source of phosphorus(I) in its reaction with Na[NV(N[tBu]Ar)3

A metal-free catalyst born of frustration Boron (a Lewis acid) and nitrogen or phosphorus fragments (both Lewis bases) tend to pair up. Keeping them separated on opposite ends of the same molecule creates a “frustrated” Lewis pair. Such molecules
