The ruthenium-catalyzed oxidation of cyclic acetals with tert-butyl hydroperoxide under mild conditions gives the corresponding glycol monoesters efficiently.The present oxidation reaction provides a useful method for the synthesis of glycol monoesters from 1-alkenes by combination with palladium-catalyzed acetalization of 1-alkenes.

The development of an unprecedented chemoselective transformation has contributed to forming a novel synthetic process for target molecules. Chemoselective oxidation of aromatic acetals has been accomplished using a reusable palladium on carbon catalyst under atmospheric oxygen conditions to form ester derivatives with tolerance of aliphatic acetals and ketals.
Interfacially cross-linked reverse micelles as soluble support for palladium nanoparticle catalysts

Reverse micelles (RM) were formed in heptane/CHCl3 with a surfactant carrying the triallylammonium (=triprop-2-en-1-ylammonium) head group (Scheme). Photo-cross-linking with dithiothreitol (=rel-(2R,3R)-1,4- dimercaptobutane-2,3-diol; DTT) captured the RMs and afforded organic, soluble nanoparticles in a one-step reaction. Similar to dendrimers, the cross-linked reverse micelles could encapsulate palladium nanoparticles within their hydrophilic cores and protect them in catalytic reactions. Good to excellent yields were obtained in the Heck coupling of a range of alkyl acrylates (=alkyl prop-2-enoates) and iodobenzenes (Tables 1 and 2). The catalytic activity of the palladium nanoparticles was maintained in several repeated runs.
