1. Rhodium catalysed hydroformylation of unsaturated esters

Author

Clarke, Matthew L.

Subjects
*RHODIUM catalysts, *HYDROFORMYLATION, *ESTERS, *CATALYSIS
Abstract

Rhodium catalysed hydroformylation of unsaturated esters has been studied. A pronounced temperature dependence was observed on the regioselectivity and catalytic activity for these reactions, and under the appropriate conditions, it is possible to obtain preferentially either linear or quaternary products. A quaternary selective hydroformylation of methyl atropate to give 1,3-aldehydic esters has also been developed. [Copyright &y& Elsevier]

2. A rationally designed cocatalyst for the Morita–Baylis–Hillman reaction

Author

Jones, Charlotte E.S., Turega, Simon M., Clarke, Matthew L., and Philp, Douglas

Subjects
*UREA, *NITROGEN excretion, *CHEMICAL reactions, *HYDROGEN bonding, *ELECTROPHILES
Abstract

Abstract: The application of electronic structure calculations to a key transition state in the reaction manifold of the Morita–Baylis–Hillman reaction allows the design of two bis(thiourea) cocatalysts capable of accelerating this reaction through the hydrogen bond mediated recognition of both the nucleophile and the electrophile.
