A new method for the chemo- and stereoselective conversion of allylic alcohols into the corresponding cyclopropane derivatives has been developed. The cyclopropanation reaction was carried out with an unprecedented titanium carbenoid generated in situ from Nugent's reagent, manganese and methylene diiodide. The reaction involving the participation of an allylic hydroxyl group, proceeded with conservation of the alkene geometry and in a high diastereomeric excess. The scope, limitations and mechanism of this metal-catalysed reaction are discussed. This journal is
Oxidative esterification of alkenes via π- and σ-organopalladium complexes: New pathways for the reaction
Kozitsyna, N.Yu.,Bukharkina,Martens,Vargaftik,Moiseev

New mechanistic data on the oxidative esterification of alkenes were obtained in the study of the reaction of Pd(II) acetate with hex-1-ene, methylcyclohex-1-ene and racemic α-pinene in a chloroform solution. High yields of unsaturated esters with terminal alcohol group were found in the oxidation of hex-1-ene, while the exocyclic methyl groups in methylcyclohex-1-ene and α-pinene remain untouched.
Rhodium promoted isomerisation of allylic alkoxides: A new method for enolate anion formation
Gazzard, Lewis J.,Motherwell, William B.,Sandham, David A.
, p. 979 - 993 (2007/10/03)
Transition metal mediated isomerisation of allylic alkoxides is presented as a new method for enolate anion generation. The scope and limitations of enolate formation with the catalysts [Rh(dppe)(THF)2]+ClO4- and (Ph3P)3RhCl are explored and the synthetic potential of the methodology demonstrated in the stereoselective formation and reactions of certain ketone and aldehyde enolates.
