A novel [3+2] annelation between ortho-carboranyltrimethylsilane and conjugated carbonyl compounds

Article abstract of DOI:10.1002/anie.199703671

Carborane-annulated cyclopentanols were produced by the reaction between 1,2-carboranes as dianionic C₂ building blocks and α,β-unsaturated ketones or aldehydes as dicationic C₃ units to five-membered carbocycles.
