A novel reduction reaction for the conversion of aldehydes, ketones and primary, secondary and tertiary alcohols into their corresponding alkanes

A novel one-pot reaction has been developed for the reduction of aldehydes, ketones and primary, secondary and tertiary alcohols into their corresponding alkyl function. This is also the first reported method which can efficiently reduce primary, secondary, or tertiary alcohols, without affecting carbon-carbon double bonds, into their corresponding alkyl function in high yields. The reduction utilises either diethylsilane or n-butylsilane as the reducing agent in the presence of the Lewis acid catalyst tris(pentafluorophenyl)borane.

Effect of tether length on Ti(III)-mediated cyclization of epoxyalkenes and unsaturated epoxyketones

The chemo- and regioselectivity of the radical cyclization induced by titanocene chloride of a series of epoxyalkenes and another of unsaturated epoxyketones are investigated. 5-Exo and 6-exo cyclizations are the main processes with epoxyalkenes. 3-Exo and 4-exo cyclizations onto the carbonyl group and 6-exo and 8-endo onto the carbon-carbon double bond are the preferred processes with epoxyenones. A tandem reaction, 6-exo onto C=C, followed by a 3-exo onto C=O, and a disfavored 5-endo cyclization onto C=C are reported.

THE HYDRIDOPENTACYANOCOBALTATE ANION INDUCED DEOXYGENATION OF ALLYLIC ALCOHOLS USING β-CYCLODEXTRIN AS A PHASE TRANSFER AGENT

β-Cyclodextrin promotes the deoxygenation of allylic alcohols to olefins using hydrogen and the in situ generated hydridopentacyanocobaltate anion.Internal olefins, of trans-stereochemistry, are the principal reaction products (i. e., no cis-products are formed).

Reductive Deoxygenation of α,β-Unsatured Ketones via Cyanophosphates by Lithium in Liquid Ammonia

A new method for deoxygenation of α,β-unsatured ketones via cyanophosphates by lithium metal in liquid ammonia is described

Reductive Displacement of the Acetate Group in Allyl, Propargyl, and Benzyl Acetates by NaBH4/NiCl2 * 6H2O

The combination of NiCl2 *6H2O and NaBH4 provides an effective system for reductive removal of the acetate group of allyl, propargyl, and benzyl acetates.Sterically less hindered allyl acetates are converted preferentially to the corresponding alkanes (Table 1).

Reductive displacement of allylic acetates by hydride transfer via catalytic activation by palladium(0) complexes

Allylic acetates are reduced to alkenes by reductive displacement by hydride reagents via catalytic activation with Pd(0) complexes. In the absence of hydrides, allylic acetates afford conjugated dienes in DMSO solvent.
