N-Donor stabilized tin(II) cations as efficient ROP catalysts for the synthesis of linear and star-shaped PLAs via the activated monomer mechanism

N-donor stabilized tin(II) cations were synthesized by a chloride abstraction from neutral complexes or by an auto-ionization concept. Prepared tin(II) cations are universal catalysts for the production of linear and star-shaped PLAs via ROP.

Higher stability of metalloid tin clusters obtained via the cation–anion interaction

The reaction of SnCl with the bulky substituents HyptBuMe2 and HypEt3 leads to the formation of two isostructural Sn10-clusters, showing novel coordination polymers in the solid state and high thermal stability in solution.

Application of ferrocene-bridged N-heterocyclic carbene stabilised bis-phosphinidenes in Sn(II) complexation

Isolation of new bidentate NHCP ligands was achieved by reaction of a bis(dichlorophosphine) with a NHC and subsequent dichlorination. The NHCPs were used in synthesis of stannyliumylidenes, transmetalation, as well as Sn(II) transfer reaction.

Tin(IV) fluoride complexes with neutral phosphine coordination and comparisons with hard N- and O-donor ligands

Abstraction of fluoride from tin(IV) fluoride complexes bearing neutral phosphine ligands yields mono, di- and tri-fluoride complexes with retention of two phosphines, whereas with neutral O- and N-donor trifluoride cations, dications are formed.

About this collection

Tin: Modern chemistry of an element from antiquity

This collection of articles in Dalton Transactions focuses on the inorganic, metalorganic and organometallic chemistry of the heavier Group 14 element, tin. As an element, tin has been exploited by humanity for over 5000 years, since it was realised that its alloy with copper provided an even more durable material, bronze. In more recent times, and throughout the half century of Dalton Trans., tin has played, and continues to occupy, a central role in the development of many of our current perspectives on the bonding and application of the whole gamut of main group element chemistry.   

Guest edited by Mike Hill (University of Bath) and John McGrady (University of Oxford), this collection of reports reflects our prevailing interest in an element that has played a central role not only in the development of modern chemistry but in human history. Both of the commonly accessible (II) and (IV) oxidation states are represented by this compendium of reports, which span fundamental studies of bonding and structure to emerging applications in small molecule activation, catalysis and materials science.

Articles will be added to this themed collection as soon as possible after they are published. Please return to this page frequently to see the collection grow.
