Rhodium-Catalyzed Carbonylative Coupling of Alkyl Halides with Phenols under Low CO Pressure

A rhodium-catalyzed carbonylative transformation of alkyl halides under low pressure of CO has been developed. This robust catalyst system allows using phenols as the carbonylative coupling partner and, meanwhile, exhibits high functional group tolerance and good chemoselectivity. Substrates even with a large steric hindrance group or multiple reaction sites can be selectively converted into the desired products in good to excellent yields. A gram-scale experiment was performed and delivered an almost quantitative amount of the product. Control experiments were performed as well, and a possible reaction mechanism is proposed.

Substituted butenylindium generated by transmetalation of cyclopropylmethylstannane with indium iodide: Synthesis and characterization of monobutenylindium

Transmetalation between substituted cyclopropylmethylstannanes and indium iodide provided the corresponding mono- and dibutenylindium species. The bulky substituent on a cyclopropyl ring selectively afforded the monobutenylindium species, which allowed th

Conjugate addition of allylic groups to α,β-unsaturated carbonyl compounds via (η3-allyl)Fe(CO)2NO complexes

(η3-Allyl)Fe(CO)2NO complexes undergo conjugate addition to α,β-unsaturated carbonyl compounds to give the corresponding δ,ε-unsaturated carbonyl compounds in good yields.The reaction of (η3-1- or 2-trimethylsiloxyallyl)Fe(CO)2NO complexes with α,β-unsaturated ketones affords 1,6- or 1,5-diketones, respectively. (η3-1-Acetonylallyl)Fe(CO)2NO complexes also react with α,β-unsaturated carbonyl compounds to give 1,8-dicarbonyl compounds.The mechanisms and reactivity of these conjugate addition reactions are discussed.Key words: Iron; Carbonyl; Allyl; Silicon; Nitrosyl; Ketone

Preparation and Reactivities of (η3-1- and 2-Trimethylsiloxyallyl)Fe(CO2)NO Complexes. Intermediates Functioning as Equivalents of β- and α-Acyl Carbocations and Acyl Carbanions

(η3-1- and 2-Trimethylsiloxyallyl)Fe(CO)2NO complexes were prepared by the reaction of the corresponding siloxyallylic halides with Bu4N.These complexes reacted with both of carbon nucleophiles and carbon electrophiles preferentially at the less hindered sites of the allylic ligands.In these reactions, (η3-1-trimethylsiloxyallyl)Fe(CO)2NO complexes served as synthetically equivalent synthons for both of β-acyl carbocations and β-acyl carbanions and (η3-2-trimethylsiloxyallyl)Fe(CO)2NO complexes as both of α-acyl carbocations and α-acyl carbanions.The stereochemical courses of the reactions are described.
