Part I.--Complexes of dimethylsulfoniumcyclopentadientylide and tetramethylenesulfoniumcyclopentadienylide with metal ions were studied in order to determine the coordination site on the ylids. Infrared spectra indicate that the ylids are coordinated through the cyclopentadienyl ring in all complexes except for the Hg(CN)2 complexes. Coordination-of the HgI2, CdI2, ZnCl2, and AgNO3 complexes is through the number one position on the ring as suggested by NMR data. Infrared and NMR data strongly indicate that the ylids in the Hg(CN)2 complexes are coordinated through sulfur. Part II.--The only method given in the chemical literature for the preparation of boron tricyanide could not be duplicated in our laboratory. A reinterpretation of the reported infrared spectrum of the substance claimed to be boron tricyanide casts doubt on the validity of this synthesis. Other reactions were investigated in order to prepare the compound, but only partial substitution with cyano groups was accomplished.
