3,5-Bis(trifluoromethyl)phenyl sulfones in the Julia-Kocienski olefination - Application to the synthesis of tri- and tetrasubstituted olefins
Alonso, Diego A.,Fuensanta, Monica,Najera, Carmen
, p. 4747 - 4754 (2007/10/03)
3,5-Bis(trifluoromethyl)phenyl (BTFP) sulfones 8a-d are successfully employed in the modified Julia olefination reaction with carbonyl compounds employing phosphazene base P4-tBu at room temp. in THF, affording tri- and tetrasubstituted olefins in good yi
Aryl and vinyl cyclopropanes through the in situ generation of B- cyclopropyl-9-BBN and its Suzuki-Miyaura coupling
Soderquist, John A.,Huertas, Ramon,Leon-Colon, Gisela

Dihydroboration of propargyl bromide with 9-BBN-H followed by treatment of the adduct with aqueous sodium hydroxide affords the hydroxy(cycloropropyl)borate complex (1), which undergoes efficient palladium-catalyzed cross-coupling to produce a variety of aryl and vinyl cyclopropanes (2) in good to excellent yields.

THERMAL ISOMERIZATION OF 2-ARYL-3,3-DIHALOGENO-1,1-DICYCLOPROPYLCYCLOPROPANES
Molchanov, A. P.,Kostikov, R. R.
, p. 1930 - 1935 (2007/10/02)
When heated, 2-aryl-3,3-dihalogen-1,1-dicyclopropylcyclopropanes are converted into 1-aryl-2,6-dihalogeno-3-cyclopropyl-1,3-hexadienes.Electron-donating substituents in the aromatic ring increase and electron-withdrawing substituents decrease the isomeriz
