This paper discusses the N-heterocyclic carbene (NHC)-catalyzed redox monoacylation of 1,n-linear diols using α-benzoyloxyaldehydes. The reactions afforded monoacylated diols in moderate to good selectivities and chemical yields. Our original NHC bearing

Two new water-soluble diphosphacyclooctanes been synthesized and characterized by NMR and surface tension measurements. Both phosphanes proved to coordinate rhodium in a very selective way as well-defined bidentates were obtained. When used in Rh-catalyzed hydroformylation of terminal alkenes, both ligands positively impacted the reaction chemoselectivity.
METHOD FOR PRODUCING ALPHA-ACYLOXYCARBONYL COMPOUND AND NOVEL ALPHA-ACYLOXYCARBONYL COMPOUND

Page/Page column 12-13, (2013/02/27)
A method for producing an α-acyloxycarbonyl compound of the present invention includes performing an intermolecular reaction between a carboxylic acid and a carbonyl compound selected from the group consisting of ketones, aldehydes, and esters, which have

It′s the iodine: The intra- and intermolecular title reaction is catalyzed by an in situ generated ammonium (hypo)iodite species. Either H 2O2 or tert-butyl hydroperoxide (TBHP) can be used as an environmentally benign oxidant and a wide range of substrates react to give the corresponding α-acyloxycarbonyl compounds in good to excellent yields.

The treatment of aldehyde enol silyl ethers 1 with lead(IV)acetate (LTA) using methylene chloride as solvent gives rise to the production of α-acetoxy aldehydes 2 and glycolic ester derivatives 3 or enals 5.Structrural variations in 1 are used to explained the divergent trends.When 1 is treated with LTA/KOAc/AcOH, high yields of the corresponding α-acetoxy aldehydes 2 are obtained with the formation of 3 and 5 being subverted.
