Substitution of allylic alcohols to form a carbon-carbon bond is accomplished by a simple reaction of the allylic alcohol itself with an enoxysilane, catalyzed by [Ir(cod)(PPh3)2]X which is activated by H2 molecule. The anion part X of the complexes plays an important role to enhance the rate and product yields of the reactions. The efficacy of the catalyst increases with switching X in the order of PF6-4--.

Azidation: Siloxy groups derived from secondary and tertiary benzyl alcohols can be transformed into azide groups at room temperature using TMSN3 in the presence of an iron catalyst (see scheme; TMS=trimethylsilyl). Secondary and tertiary benzy
A Practical Method for Activation of Commercial Lithium Hydride: Reductive Silylation of Carbonyl Compounds with Lithium Hydride and Chlorotrimethylsilane

Commercially available lithium hydride, an essentially inert metal hydride, can be activated as a hydride source by an equimolar amount of chlorotrimethylsilane and a catalytic amount of a Zn salt or Zn powder.Aromatic and aliphatic ketones, as well as no

An optically active allylsilane (R)-(E)-1-phenyl-1-(trimethylsilyl)-2-butene (1) (81percent ee) was allowed to react with m-chloroperoxybenzoic acid (MCPBA) in dichloromethane to give, after acidic methanolysis, (S)-(E)-4-phenyl-3-buten-2-ol (2) (71-73per
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.
