Laying the Groundwork for a Tantalum Dearomatization Agent

Chapter 1 provides a brief description of the synthesis of the -basic dearomatization agents {Os(NH3)5}, {TpRe(CO)L} (L=tBuNC, PMe3, py, MeIm, and NH3) and {TpW(NO)(PMe3)}. It also submits a theoretical explanation for the phenomenon of dearomatization via back bonding. The basic principles for the synthesis of a dearomatization agent that have been derived from these past syntheses are discussed in the context of the characteristics that we hoped to design into a new tantalum based dearomatizing metal fragment.
