Synthesis of Unsaturated Silyl Heterocycles an Intramolecular Silyl-Heck Reaction. | LitMetric

Synthesis of Unsaturated Silyl Heterocycles an Intramolecular Silyl-Heck Reaction.

Organometallics

Department of Chemistry and Biochemistry, University of Delaware, Newark, Delaware 19716, United States.

Published: October 2019

We report the synthesis of unsaturated silacycles an intramolecular silyl-Heck reaction. Using palladium catalysis, silicon electrophiles tethered to alkenes cyclize to form 5- and 6-membered silicon heterocycles. The effects of alkene substitution and tether length on the efficiency and regioselectivity of the cyclizations are described. Finally, through the use of an intramolecular tether, the first examples of disubstituted alkenes in silyl-Heck reactions are reported.
