The utilisation of the PNP iridium pincer complex [Ir(PNP)(COE)][BF4] [PNP = 2,6-bis{(di-tert-butylphosphino)methyl}pyridine; COE = cyclooctene] in the sp3 C–H activation of methyl propanoate and other related esters was explored.

Sticking and patching: tuning and anchoring cyclometallated ruthenium(II) complexes
In a series of [Ru(bpy)2(C^N)][PF6] complexes with a variety of functionalities in the cyclometallating ligand, the absorption response is enhanced considerably by the introduction of a 4-C6H4P(O)(OEt)2 anchoring domain in the C^N pyridine ring.

About this collection
Professor Kenneth Wade, F.R.S. 13th October 1932–16th March 2014
This themed collection of 60 Dalton Transactions articles is dedicated to Ken Wade, who very unexpectedly passed away on 16th March 2014. While this sad loss is the reason for this commemoration, it is an honour for me to Guest Edit this collection.
The collection covers a wide and diverse spectrum of topics spanning inorganic chemistry, something that very clearly demonstrates Ken’s significant and wide-ranging contributions to inorganic chemistry in its broadest context. The rapidity with which all of the invited authors agreed to contribute their work to this themed collection of articles unmistakably reflects the great esteem and friendship with which Ken was held, and provides a fitting tribute to the man himself, his huge role as a teacher and mentor, and his important and extensive contributions to chemistry. Without a doubt, Ken is very sorely missed.
