The concept of "umpolung"reactivity of π-allylmetal complexes has been developed as a powerful method for the allylation of aldehydes. This paper describes the photocatalytic umpolung strategy for the synthesis of nucleophilic allylcobalt complexes through a single-electron-transfer (SET) process. This strategy enables the metallaphotoredox allylation of carbonyls with allyl acetate using organic N,N-diisopropylethylamine as the terminal reductant bypassing the use of a stoichiometric amount of metals. Ultraviolet-visible spectroscopy was used to monitor the redox changes of cobalt in the reaction.
MnO2as a terminal oxidant in Wacker oxidation of homoallyl alcohols and terminal olefins

Efficient and mild reaction conditions for Wacker-type oxidation of terminal olefins of less explored homoallyl alcohols to β-hydroxy-methyl ketones have been developed by using a Pd(ii) catalyst and MnO2 as a co-oxidant. The method involves mild reaction conditions and shows good functional group compatibility along with high regio- and chemoselectivity. While our earlier system of PdCl2/CrO3/HCl produced α,β-unsaturated ketones from homoallyl alcohols, the present method provided orthogonally the β-hydroxy-methyl ketones. No overoxidation or elimination of benzylic and/or β-hydroxy groups was observed. The method could be extended to the oxidation of simple terminal olefins as well, to methyl ketones, displaying its versatility. An application to the regioselective synthesis of gingerol is demonstrated.

The invention provides a preparation method of an ionic type bis-triphenyl organic antimony (V) complex and a method for synthesizing allyl alcohol compounds under catalysis of the ionic type bis-triphenyl organic antimony (V) complex. The complex is a cationic type organic antimony complex, wherein two antimony atoms in the complex are bridged by virtue of oxygen atoms and are pentavalent; and each antimony atom is in coordination with one water molecule, and an ionic bond is formed by the entire organic antimony cationic part with corresponding anions. The synthetic method comprises the following step: by taking the bis-triphenyl organic antimony (V) complex as a catalyst, taking a commonly-used organic solvent as a reaction solvent, and taking aldehyde and tetraallyltin as raw materials, performing reaction. The synthetic method can be used for providing a novel low-cost and 'green' route for preparing the allyl alcohol compounds, and has the advantages that target product selectivity and yield are high, the catalyst can be repeatedly used, corresponding ketone can be obtained by performing simple column chromatography separation on the product, and the whole reaction and separation process is simple to operate and is green and environment-friendly.
