Abstract
Thermolysis of Cp2Ti (CH2SiMe3) 2 in the presence of Me3SiC CSiMe3 forms tris (trimethylsilyl) titanacyclobutene. Unlike other titanacyclobutenes which undergo insertion with carbonyl compounds, this reagent serves as a precursor to Cp2Ti CHSiMe3, converting carbonyl compounds to the corresponding alkenyl silanes. This olefination takes place under mild conditions even at room temperature and works with aldehydes, ketones ...
