Abstract Weakly coordinating anions (WCAs) are considered promising candidates for application as electrolytes in multivalent post‐lithium batteries. One strong candidate electrolyte salt Mg battery is [Mg(L) x ][Al(OR F ) 4 ] 2 (L=MeCN (acetonitrile), DME (1,2‐dimethoxyethane); =3, 6; R =C(CF 3 that contains [Al(OR − one of the least WCAs known. Here we present a novel synthetic route, which vibrational, NMR and XRD analyses show formation clean, pristine without common contaminants found...

Syntheses and characterization of two salts [(L)GaGa(L)][pf]2 ([pf]- = [Al(ORF)4]-; RF C(CF3)3) are reported. They include the first dicationic digallene [(L)Ga⇆Ga(L)]2+ (L CDPPh C(PPh3)2) a digallane [(L)Ga-Ga(L)]2+ [NacNacMes]-). The CDPPh-supported dication includes trans-bent [L-GaGa-L]2+ bond that is analogous to neutral R-GaGa-R molecules related Robinson's famous "Digallyne" [R-GaGa-R]2-. widely used "Jones magnesium dimer", but very short GaII-GaII single bond.

Abstract The earth‐metal olefin complex [Ga I (COD) 2 ] + [Al(OR F ) 4 − (COD=1,5‐cyclooctadiene; R =C(CF 3 constitutes the first homoleptic of any main‐group metal accessible as a bulk compound. It is straight forward to prepare in good yield and an that—similar many transition‐metals—may adopt +1 +3 oxidation states opening potential applications. Crystallographic‐, vibrational‐ computational investigations give insight atypical bonding between metal. They are compared classical...

Abstract In this work, we present the solid‐state structures of solvent‐free Ga[ pf ] and In[ salts ([ − =[Al(OR F ) 4 ; R =C(CF 3 ), which are very rare examples with truly ‘naked’ metal cations. Both may serve as starting materials for subvalent gallium indium chemistry weakly coordinating ligands providing freedom choice solvents future. On other hand, report rationalize formation isolation [M(OEt 2 ][ [M(MeCN) (M=Ga, In), underlining surprising stability these group 13 M + ions against...

Abstract This review addresses the coordination chemistry (mainly) enabled by using univalent [M(fluoroarene) 2–3 ] + [Al(OR F ) 4 − ‐salts (M=Ga, In; R =C(CF 3 as robust starting materials. In course of this work, it became clear that orbital energy n s 2 (n=4, 5) lone pair in such [:M(L) cations reacts drastically depending on quality ligand employed. Activation with strong σ‐donor ligands might be used for bond activation and oxidative addition reactions. Yet, unexpectedly, sterically...

Already 1 mol% of subvalent [Ga(PhF)2]+[pf]- ([pf]- = [Al(ORF)4]-, RF C(CF3)3) initiates the hydrosilylation olefinic double bonds under mild conditions. Reactions with HSiMe3 and HSiEt3 as substrates efficiently yield anti-Markovnikov anti-addition products, while bulkier such HSiiPr3 are less reactive. Investigating underlying mechanism by gas chromatography STEM analysis, we unexpectedly found that H2 metallic Ga0 formed. Without addition olefins, formation R3Si-F-Al(ORF)3 (R alkyl), a...

Over recent decades, the West Antarctic Ice Sheet (WAIS) has witnessed a large increase in ice shelf melting. This loss is recognized to be associated with response changes ocean state, particular of Circumpolar Deep Water (CDW) on Amundsen Sea continental shelf. It been shown that variability CDW inflow strongly related wind changes. While instrumental-based atmospheric reanalysis products are available since 1979, given strong natural climate, this period few decades might too short...
