Organometallic element

This work is focused on unusual reactions of the novel metallocene reagents Cp2M(L)(ti2-Me3SiC2SiMe3), which often give very clean organometallic elemental reactions, as the basis for applications in organic synthesis.

The PRDDO (partial retention of diatomic differential overlap) method is an attempt to get the optimal ratio of accuracy to CPU time. It has been parameterized for the periodic elements through Br, including the 3rd row transition metals. It was parameterized to reproduce ah initio results. PRDDO has been used primarily for inorganic compounds, organometallics, solid-state calculations, and polymer modeling. This method has seen less use than other methods of similar accuracy mostly due to the fact that it has not been incorporated into the most widely used semiempirical software. 

The fundamental Ziegler-Natta recipe consists of two components the halide or some other compound of a transition metal from among the group IVB to VIIIB elements and an organometallic compound of a representative metal from groups lA to IIIA. Some of the transition metal compounds that have been...

The organometallic chemistry of this group developed rather slowly but there has been a surge of interest, especially in Nb and Ta, in the last decade or so. The chemistry of a alkyls or aryls is less well developed than for many other elements but [V CH(SiMe3)2 3], [V (CH2SiMe3)4], and...
