A new method for nitrogen fixation involved the treatment of titanium tetraisopropoxide with lithium metal and trimethylsilyl chloride in the presence of a nitrogen atmosphere to give either a titanium-nitrogen complex and/or N(TMS)3 9 (proposed structures) <04BCJ1655>. This reagent was utilized to prepare pyrrole, indoles, and other nitrogen heterocycles. For example, treatment of preformed 9 with enol triflate 8 led to fused pyrrole 10. [Pg.110]
