Halogenated closo-Dodecaborate Anions Stabilize Weakly Bound [(Me3NH)3X]2+ (X = Cl, Br) Dications in the Solid State

Cocrystallization of [Me3NH]2[B12Y12] (Y = Cl, Br, I) with 1 equiv. of [Me3NH]X (X = Cl, Br) from acetonitrile/diethyl ether solution produced large colorless single crystals of [(Me3NH)3X][B12Y12]. Four different compounds of this type were prepared and structurally characterized. The compounds consist of weakly coordinating perhalogenated closo-dodecaborate [B12Y12]2– dianions and unprecedented weakly bound discrete [(Me3NH)3X]2+ dications. The [(Me3NH)3X]2+ dications are built up from a central halide anion and three [Me3NH]+ cations bound by N–H···X hydrogen bonds. The cations have a pyramidal structure, as determined by X-ray diffraction, which is in contrast to quantum-chemical calculations, which predict a trigonal-planar structure. While the [(Me3NH)3Cl]2+ and [(Me3NH)3Br]2+ cations were easily prepared, attempts to synthesize the corresponding [(Me3NH)3F]2+ and [(Me3NH)3I]2+ cations failed. Three further crystal structures containing the angulated [(Me3NH)2X]+ cation stabilized by [B12Cl12]2–, [B12Br12]2–, or [Me3NB12Cl11]– are reported as well.

Hybrid germanium iodide perovskite semiconductors: Active lone pairs, structural distortions, direct and indirect energy gaps, and strong nonlinear optical properties

The synthesis and properties of the hybrid organic/inorganic germanium perovskite compounds, AGeI3, are reported (A = Cs, organic cation). The systematic study of this reaction system led to the isolation of 6 new hybrid semiconductors. Using CsGeI3 (1) as the prototype compound, we have prepared methylammonium, CH3NH3GeI3 (2), formamidinium, HC(NH2)2GeI3 (3), acetamidinium, CH3C(NH2)2GeI3 (4), guanidinium, C(NH2)3GeI3 (5), trimethylammonium, (CH3)3NHGeI3 (6), and isopropylammonium, (CH3)2C(H)NH3GeI3 (7) analogues. The crystal structures of the compounds are classified based on their dimensionality with 1-4 forming 3D perovskite frameworks and 5-7 1D infinite chains. Compounds 1-7, with the exception of compounds 5 (centrosymmetric) and 7 (nonpolar acentric), crystallize in polar space groups. The 3D compounds have direct band gaps of 1.6 eV (1), 1.9 eV (2), 2.2 eV (3), and 2.5 eV (4), while the 1D compounds have indirect band gaps of 2.7 eV (5), 2.5 eV (6), and 2.8 eV (7). Herein, we report on the second harmonic generation (SHG) properties of the compounds, which display remarkably strong, type I phase-matchable SHG response with high laser-induced damage thresholds (up to 3 GW/cm2). The second-order nonlinear susceptibility, S(2), was determined to be 125.3 ± 10.5 pm/V (1), (161.0 ± 14.5) pm/V (2), 143.0 ± 13.5 pm/V (3), and 57.2 ± 5.5 pm/V (4). First-principles density functional theory electronic structure calculations indicate that the large SHG response is attributed to the high density of states in the valence band due to sp-hybridization of the Ge and I orbitals, a consequence of the lone pair activation.

SUBSTITUTION OF THE ANION IN AMMONIUM AND PHOSPHONIUM CHLORIDES BY THE ACTION OF ELECTROPHILIC AGENTS

N,N-Dialkylmethaniminium iodides were obtained by the reactions of N,N-dialkylmethaniminium chlorides with methyl iodide.The reactions of ammonium and phosphonium chlorides with triethyloxonium tetrafluoroborate, dimethyl sulfate, methyl tosylate, and methyl iodide take place with substitution of the chloride ion by the BF4-, CH3SO3O-, p-CH3C6H4SO3- or I- ions.Substitution of the chloride ion of phosphonium salts by the iodide ion can be realized by the action of trimethyliodosilane.

REACTIVITE PHOTOCHIMIQUE DES DIALKYLAMINO-2 CYCLOHEXENE-2 ONES ET DES SELS D'AMMONIUM CORRESPONDANTS

Photolysis of 2-dialkylamino-2-cyclohexenones leads to α-ketoazetidines.The reactivity of 3-methyl-2-dialkylamino-2-cyclohexenones and the effect of the nature of the dialkylamino groups on the photocyclization are discussed.Photolysis of the corresponding ammonium salts in hydroxylic solvents led only to adduct formation.

The Mechanism of Photolysis of Some Benzyltrimethylammonium Salts in Water and in Alcohols

Photolysis of a range of benzyltrimethylammonium and 3,5-dimethoxybenzyltimethylammonium salts in water or methanol at 253.7 nm gave typically benzyl alcohols (or benzyl methyl ethers), toluenes, bibenzyls and isomers, and di- and tri-methylammonium salts.By detailed sensitisation and quenching experiments it was established that, in the photolysis of benzyltrimethylammonium bromide in aqueous t-butyl alcohol, benzyl t-butyl ether, benzyl alcohol, and some toluene were produced by a singlet pathway and bibenzyl by a triplet pathway.A general mechanistic scheme for all the photolyses studied is thus suggested.

Stereochemistry of Photosolvolysis of (-)-1-Phenylethyltrimethylammonium Iodide in Water and in Methanol, and Nucleophile Capture Ratios during Photosolvolysis of Some Benzylammonium Salts

The photosolvolysis of (-)-1-phenylethyltrimethylammonium iodide in water or methanol is characterised by extensive racemisation accompanied by some net configurational inversion, a result similar to that generally observed in thermal solvolysis via ion-pairs at chiral secondary centres.Recovered quaternary salt from the photolysis in water is only slightly if at all racemised, while likewise there is no observable epimerisation at nitrogen in recovered benzylammonium salts following photolysis in methanol of suitable derivatives of camphidine, trans-decahydroquinoline, and 4-phenylpiperidine.A strong preference for formation of the methyl ether rather than the alcohol is exhibited on either photochemical or thermal solvolysis of 1-p-methoxyphenylethyltrimethylammonium iodide in aqueous methanol, but nucleophile capture ratios during photosolvolysis of simple benzyltrimethylammonium salts in this mixed solvent system are much lower.
