New reactions of β-diketiminatolanthanoid complexes: sterically induced self-deprotonation of β-diketiminato ligands
Attempted synthesis of sterically demanding bis- or tris-β-diketiminato complexes of lanthanoids resulted in ligand deprotonation and the formation of complexes containing both a “normal” and a deprotonated ligand; one of these on protonation gave the first cationic β-diketiminato–Ln complex.

About this collection
Michael F. Lappert, one of the giants of 20th century organometallic chemistry, sadly passed away in March 2014.
To honour his memory, and significant contribution to chemistry, members of the Dalton Transactions and ChemComm Editorial Boards have curated this collection of selected publications. Together, these papers highlight his broad interests and ability for pursuing seminal research.
All articles in the collection are free to access until October 2015 and are introduced in a dedicated Editorial written by Professors John Arnold, Penny Brothers, Philip Mountford, Warren Piers, Christine Thomas and Don Tilley.
