A new nucleophilic isopropyl transfer reagent, triisopropylsulfoxonium tetrafluoroborate, has been prepared and evaluated. Thus, using this reagent and NaH in DMF, a range of electron deficient alkenes, including several chalcone analogues, α,β-unsaturated ketones, dienones and quinones, plus α,β-unsaturated esters, nitrile, sulfone and nitro examples, have been converted into the corresponding gem-dimethylcyclopropane compounds.
The effects of triplet sensitizers' energies on the photoreactivity of β,γ-unsaturated methyl ketones

(Chemical Equation Presented) Triplet determines reactivity: β,γ-Unsaturated ketones 1 do not undergo the oxa-di-π-methane (ODPM) rearrangement in the presence of acetophenone or 3-methoxyacetophenone as a triplet sensitizer. However, they afford the ODPM
A novel route to cyclopropyl ketones, aldehydes, and carboxylic acids
Rodriques, Karen E.
, p. 1275 - 1278 (2007/10/02)
Cyclopropanation of α,β-unsaturated N-methoxy-N-methyl amides provided the cyclopropyl amides in far superior yields to those obtained with the corresponding ketones. The desired ketones are then readily accessible by the addition of organometallic reagents. Access to a variety functional groups, including aldehydes and carboxylic acids, is also described.
