The aluminum analogue of Piers’ borane, [HAl(C6F5)2]3, is prepared on a gram-scale and shown to be highly acidic, a strong hydride donor, and a catalysts for the hydrosilylation of alkynes and alkenes.

Double chloride abstraction from Cp*SbCl2 (Cp* = pentamethylcyclopentadienyl) affords an arene-stabilized η5-Cp*-bound antimony dicationic compound [(η5-Cp*)Sb(tol)][B(C6F5)4]2 (1) (tol = toluene), which exhibits strong Lewis acidity, abstracting c

The salts [(BAC)2 PO][BF4 ] (5) and [(BAC)2 PO2 ][BF4 ] (4) (BAC=bis(diisopropylamino) cyclopropenylidene), consisting of the PO+ and PO2 + cations, respectively, coordinated to the singlet carbenes, have been prepared. Computational investigations r

While (Ph2CN2)B(C6F5)3 is unstable, single electron transfer from Cp*2Co affords the isolation of stable products [Cp*2Co][Ph2CNNHB(C6F5)3] 1 and [Cp*Co(C5Me4CH2B(C6F5)3)] 2. The analogous combination of Ph2CN2 and BPh3 showed no evidence of adduct f

Double chloride abstraction of Cp*AsCl2 gives the dicationic arsenic species [(η5 -Cp*)As(tol)][B(C6 F5 )4 ]2 (2) (tol=toluene). This species is shown to exhibit Lewis super acidity by the Gutmann-Beckett test and by fluoride abstraction from [NBu4

Summary Abstraction of chloride from (Cp*PCl2) with the silylium salt [Et3Si][B(C6F5)4] afforded [(η2-Cp*)PCl][B(C6F5)4] (1), whereas further chloride abstraction using another equivalent [Et3Si][B(C6F5)4] was unsuccessful. The corresponding species

The reductive coupling of two diazomethanes is affected by reaction with [(NacNacMes )Mg]2 affording the species [(NacNacMes )Mg(N2 CPh2 )]2 2 and [(NacNacMes )Mg(N2 C(C6 H4 )2 )]2 3. These species containing N4 linkages readily evolve the central N2

A room-temperature-stable crystalline cyclic (alkyl)(amino)nitrenium cation 2 features cationic nitrogen atom with a smaller HOMO-LUMO gap compared to that of a 1,2,3-triazolium 5 (an N-heterocyclic nitrenium cation). The low-lying LUMO of 2 results

Varying the reaction ratio of cyclic (alkyl)(amino) carbene (cAACEt) with AlH3·NEtMe2 leads to the isolation of (cAACEtH)AlH2·NEtMe21 and (cAACEtH)2Al(μ-H)2AlH2·NEtMe22 and the first example of a monomeric dialkyl-aluminum hydride (cAACEtH)2AlH 3
