Cl (V), 3>Cl (VII) and the 1,3,5-trithiacyclohexane derivative (CHS)3(CH2CH2Cl)3 (IX) react with NaAs(C6H5)2 in liquid ammonia to give N2CH2CH(CH3)As(C6H5)2 (VI), N3 (VIII) and (CHS)33 (X).Treatment of VI with HI results, under elimination of benzene, almost quantitatively in the formation of I (XI), which is recristallized from THF as I*THF (1/1) (XIa).All attempts to obtain homogeneous products by reaction of VIII or X with HI, such as 3>I and (CHS)3(CH2CH2AsI2)3, failed.With H2O/NH3 or H2S/N(C2H5)3 XIa forms the cryptands 8(As4O4)6 (XII) or 8(As4O4)6 (XIII), which also can be considered as spherands.All the new compounds are characterized, as far as possible, by their IR, Raman, 1H NMR and mass spectra.

Given the periodic relationship of phosphines and arsines, is remodeling the catalytic asymmetric hydrophosphination reaction an efficient manner to develop the corresponding hydroarsination reaction? Herein, a chiral PCP-Pd(ii) pincer complex adept at ge

A series of thioacylsulfanylarsines ((RCS2)AsPh2, (RCS2)2AsPh, (RCS2)3As) were synthesized by treating piperidinium dithiocarboxylates with Ph2AsCl, PhAsCl2 or AsCl3, respectively and characterized. Their molecular structures were determined by X-ray crystallography and compared with those of the corresponding acylsulfanyl derivatives ((RCOS)AsPh2, (RCOS)2AsPh, (RCOS)3As). They exist as monomers, and the environment around the arsenic atoms is distorted tetrahedral with one lone pair at the apex. The structure of the mono(dithiocarboxylate) is different from that of the corresponding thiocarboxylic acid derivative, while the bis and tris derivatives showed similar structure to the corresponding thiocarboxylic acid derivatives ((RCOS)2AsPh, (RCOS)3As), respectively. The new compounds showed intramolecular interactions between the thiocarbonyl sulfur and the central arsenic atom. NBO (Natural Bond Orbital) analyses performed on the model compounds (CH3CS2)As(CH3)2 and (CH3CS21)-(CH3CS22 )AsCH3 at the RHF/LANL2DZ level of theory showed the presence of interactions between the non-bonding orbitals on the thiocarbonyl sulfur (ns) and the σ*MS orbitals together with that between the ns and the σ*MC orbitals for the former compound; for the latter the presence of both orbital interactions between ns and σ*MS1 and between ns and σ*MS2 are present. The reaction of the mono(dithiocarboxylate) derivative (R = 4-CH3-C6H4) with piperidine in ethanol gave piperidinium diphenyldithioarsinate along with the corresponding N-thioacyl- or N-acyl-piperidine. A similar reaction of the bis(dithiocarboxylate) derivative (R = 4-CH3C6H4) gave the novel di(piperidinium) phenyltrithioarsonate in which two anion charges are delocalized on the AsS3 moiety and a cyclic phenylarsine sulfide tetramer (PhAsS)4. The diphenyldithioarsinate and phenyltrithioarsonate salts exist as a dimer and a polymer, respectively, in which 12-membered rings are formed by intermolecular N-H ... S hydrogen bonds.
