Reagents Based on Cyclopentadienyl Derivatives of the Group 14 Elements for the Synthesis of Indium(I) Derivatives. Crystal and Molecular Structure of In(C5H4SiMe3).

摘要

The cyclopentadienyltrimethyl derivatives of the group 14 elements (C5H4MMe3 M=Si, Ge, Sn) have been investigated for their effects in indium(I) chemistry. The compounds In(C5H4SiMe3) and In(C5H4GeMe3) have been prepared from the corresponding lithium cyclopentadienyl reagent LiC5H4MMe3 and Indium chloride. Characterization data have included partial elemental analyses (C,H), physical properties, infrared and 1H nuclear magnetic spectroscopic data, oxidation reactions with dilute aqueous HC1 and a single crystal X-ray structural study in the case of In(C5H4SiMe3). When cyclopentadienyltrimethyltin, C5H5SnMe3, was combined with InCl in diethyl ether, In(C5H5) and Me3SnCl were formed in good yields.
