The reaction of cyclopropanols with Burgess reagent: A reinvestigation and correction
Banert, Klaus,Ries, Monika,Schaumann, Ernst
scheme or table, p. 205 - 212 (2011/04/26)
Chemical Equation Presented The reaction of cyclopropanols with Burgess reagent yields the unusual sulfamates 8 and their N-methylated derivatives 9. Unlike a previous study, dicyclopropyl ether formation was not observed. Also, the mechanism of ether formation from a cyclopropanol precursor cannot follow an SN2 pathway with retention.

Copper-catalyzed conjugate addition of Grignard reagents in the presence of Me3SiCl and HMPA proceeds in much higher yield than the reaction of conventional organocopper reagents and shows very good regio-, stereo-, and chemoselectivities.
ACTION DES DIALKYLCUPRATES DE LITHIUM SUR LES ALDEHYDES α,β-ETHYLENIQUES
Chuit, C.,Foulon, J. P.,Normant, J. F.
, p. 2305 - 2310 (2007/10/02)
Nearly exclusive 1-4 addition products are obtained by action of lithium dialkylcuprates with α,β-ethylenic aldehydes.Non polar solvents and low temperatures favor this reaction.Only α,β-ethylenic aldehydes having a trisubstituted double bond give a relatively important proportion of 1-2 addition product.
