Synthesis, Structure, and Reactivities of Iminosulfane- and Phosphane-Stabilized Carbones Exhibiting Four-Electron Donor Ability
Iminosulfane(phosphane)carbon(0) derivatives (iSPCs; Ar3P→C←SPh2(NMe); Ar=Ph (1), 4-MeOC6H4 (2), 4-(Me2N)C6H4 (3)) have been successfully synthesized and the molecular structure of 3 characterized. Carbone 3 is the first thermally and hydrolytically stable carbone stabilized by phosphorus and sulfur ligands. DFT calculations reveal the electronic structures of 1-3, which have two lone pairs of electrons at the carbon center. First and second proton affinity values are theoretically calculated to be in the range of 286.8-301.1 and 189.6-208.3 kcal mol-1, respectively. Cyclic voltammetry measurements reveal that the HOMO energy levels follow the order of 3>2>1 and the HOMO of 3 is at a higher energy than those of bis(chalcogenane)carbon(0) (BChCs). The reactivities of these lone pairs of electrons are demonstrated by the C-diaurated and C-proton-aurated complexes. These results are the first experimental evidence of phosphorus- and sulfur-stabilized carbones behaving as four-electron donors. In addition, the reaction of hydrochloric salts of the carbones with Ag2O gives the corresponding AgI complexes. The resulting silver(I) carbone complexes can be used as carbone transfer agents. This synthetic protocol can also be used for moisture-sensitive carbone species. Getting tough on carbon: The combination of the high electron-donating ability of the triarylphosphane ligand and the strong π-acceptor ability of the iminosulfane ligand confers considerable thermal and hydrolytic stability on iminosulfane(phosphane)carbon(0) (see figure). The four-electron donor ability of these carbon complexes is revealed by the synthesis of aurated complexes.

Syntheses and Spectroscopic Investigations of Substituted cis- and trans-Dichlorobis(triphenylphospane)platinum(II) Compounds
Compounds of the type cis- and trans-dichlorobis(triphenylphosphane)platinum(II) (3) with substituents of different electronic character in the phenyl rings bonded to phosphorus have been synthesized.The coupling constants 1J and the chloro-platinum valence vibrational frequencies are demonstrated to be criteria for unambiguous discrimination between cis- and trans-configurations at platinum; a linear correlation exists between the sum of the ?-constants of the sustituents at the triphenylphosphane and the coupling constants 1J.
