In this paper we report a catalytic method to transfer formal equivalents of HF from fluoroalkanes to an alkyne. The method leads to a simple and sustainable approach to generate difluoroalkanes and tolerates numerous sensitive functional groups incl

Fluorinated gases (F-gases) are routinely employed as refrigerants, blowing agents, and electrical insulators. These volatile compounds are potent greenhouse gases and consequently their release to the environment creates a significant contribution t

Perfluoroalkyl substances (PFAS) are now pervasive in the environment. The largest single use material within the PFAS compound class is poly(tetrafluoro)ethylene) (PTFE), a robust and chemically resistant polymer. Despite their widespread use and se

Herein we present the first double deprotonation of acetonitrile (CH3CN) using a bimetallic iron-aluminium complex. The products of this reaction contain an exceeding simple yet rare [CHCN]2– dianion moiety that bridges two metal fragments. DFT cal

In this mini-review, we summarise the current examples of carbon chain production from metal formyl intermediates with homogeneous metal complexes. To date, the formation of both unsaturated and saturated C2 motifs along with cyclic C3 products has b

The activation of C–C sigma-bonds within strained three- and four-membered hydrocarbons at electrophilic Mg and Zn centres is reported. This was achieved in a two-step process involving (i) hydrometallation of a methylidene cycloalkane followed by

The reaction of an Fe–Al complex with an array of substituted pyridines is reported. Depending on the substitution pattern of the substrate site-selective sp2 or sp3 C–H bond activation is observed. A series of reaction products are observed base

The reversible activation of dihydrogen with a molecular zinc anilide complex is reported. The mechanism of this reaction has been probed through stoichiometric experiments and DFT calculations. The combined evidence suggests that H2 activation occur

The reaction of cyclopropenes with compounds containing Mg–Mg bonds is reported. 1,2-Dimagnesiation occurs exclusively by syn-addition to the least hindered face of the alkene forming a single diastereomeric product. DFT calculations support a conc

The reactions of transition metal complexes underpin numerous synthetic processes and catalytic transformations. Typically, this reactivity involves the participation of empty and filled molecular orbitals centred on the transition metal. Kinetically
