Au108S24(PPh3)16: A Highly Symmetric Nanoscale Gold Cluster Confirms the General Concept of Metalloid Clusters

The reduction of (Ph3P)AuCl with NaBH4in the presence of HSC(SiMe3)3, leads to one of the largest metalloid gold clusters: Au108S24(PPh3)16(1). Within 1 an octahedral Au44core of gold atoms arranged as in Au metal is surrounded by 48 oxidized Au atoms of an Au48S24shell, a novel building block in gold chemistry. The protecting Au48S24shell is completed by additional 16 Au(PPh3) units, leading to a complete protection of the gold core. Within 1 the Au–Au distances get more molecular on going from the center to the ligand shell. Cluster 1 represents novel structural motives in the field of metalloid gold clusters which also are partly typical for metal atoms in metalloid clusters: MnRm(n>m).

Properties of Chalcogen-Chalcogen Bonds, XVII. - Di- and Trisulfanes with Sterically Congested Alkyl Substtuents: The First trans-Dialkyldisulfane

Bistrisulfane (1) is obtained from tris(trimethylsilyl)methyllithium and sulfur with subsequent oxidation by oxygen or from tris(trimethylsilyl)methanethiol with sulfur dichloride.The solid trisulfane contains a transoid (helical) C-S-S-S-C backbone without severe distortion from steric strain.Desulfuration of the byproduct bistetrasulfane (2) with mercury provides 1, but further desulfuration of 1 to bisdisulfane (3) has not been achieved. 3 was isolated after oxidation of lithium tris(trimethylsilyl)methanethiolate with bromine. 3 contains a trans-C-S-S-C moiety with an unusually long S-S bond (210-211 pm).The less crowded bis(triphenylmethyl)disulfane (4) contains a "normal" C-S-S-C moiety with anticlinal conformation (torsion angle -110 deg).

SERENDIPITOUS SYNTHESIS OF ALKYL TRIMETHYLSILYLDITHIOFORMATES BY TRAPPING OF BIS(TRIMETHYLSILYL)THIONE WITH ALKANESULFENIC ACIDS. SYNTHESIS OF BIS- AND TRIS(TRIMETHYLSILYL)METHANETHIOLS.

Tris(trimethylsilyl)methanethiol, prepared from tris(trimethylsilyl)methane, can be easily converted into bis(trimethylsilyl)methanethiol and this to bis(trimethylsilyl)methyl alkanethiosulfinate esters; the latter upon heating afford alkyl trimethylsilyldithioformates via bis(trimethylsilyl)thione, which can be trapped with dienes.

BIS(TRIMETHYLSILYL)THIOKETONE

Tris(trimethylsilyl)methylsulphenylbromide undergoes facile Me3SiBr elimination to give bis(trimethylsilyl)thioketone.
