In an attempt to expand the scope of titanacyclobutenes, malonate-derived α,ω-alkylpropargyl dibromides and α,ω-bis(bromopropargyl) malonates were prepared and examined for their reactivity with titanocene reagents. Unfortunately, all of the α,ω-alkylpropargyl dibromomalonates failed, presumably...

Synthesis of boracyclobutenes by transmetallation; insertion and demetallation reactions of boracyclobutenes and titanacyclobutene complexes
DownloadFall 2009
A series of new titanacyclobutene complexes were prepared by samarium diiodide-mediated central carbon alkylation of η³-propargyltitanium complexes. The titanacyclobutenes were synthesized in high yield and completely characterized using NMR spectroscopy and, where applicable, single crystal...

This dissertation describes some advances that were made in the field of paramagnetic first-row transition metal complexes. Two independent topics will be discussed. The first topic that will be discussed is the preparation and reactivity of titanacylobutene complexes. Initially, the Stryker...
