Neutral vs anionic palladium iodide-catalyzed carbonylation of terminal arylacetylenes
2015, Journal of Molecular Catalysis A: ChemicalCitation Excerpt :Palladium hydrides as reducing species are reported in the literature [31]. Their intermediacy in reductive carbonylation of benzyl alcohols was proposed by Cavinato and Toniolo [66] and their reactions with allyl ether or ester were described [67]. It would appear that Pd–H species, that could justify the formation of compounds 6, 8 [58], and 9, are involved in these carbonylation processes as shown in Schemes 4 and 5.
Palladium-catalysed reactions of alcohols. Part D: Rearrangements, carbonylations, carboxylations and miscellaneous reactions
2005, TetrahedronCitation Excerpt :The acylpalladium complexes are produced from a variety of processes, and the use of an alcohol as the solvent instead of an aprotic solvent may modify the course of a reaction in trapping the acylpalladium intermediate to afford the corresponding ester.167–172 The synthesis of polyfunctionalised compounds by carbonylative esterification using two polyfunctionalised synthons has been exploited (Eq. 78),173 and the intramolecular alcoholysis of a variety of acylpalladium intermediates has been intensively reported for cyclocarbonylations to produce carbonates, lactones, butenolides, oxazolidinones and cyclic oxamates;164,174–192 the examples depicted in Eqs. 79–86 illustrate that various experimental conditions and substrates have been used. Instead of organic solvents, supercritical CO2 has been used for the intramolecular carbonylation of 2-iodobenzyl alcohol,193 whereas various ionic liquids and molten salts have been explored as solvents for the butoxycarbonylation of 4-bromoacetophenone, the best result being obtained in tetra-n-butylammonium bromide.194
