Development of new synthetic methodologies
… and p,p-disubstituted Baylis-Hillman olefines. Among these products, a-alkylidene p-amino acids have been found to serve as novel leads for the design of anf/-cancer drugs by NIH. Finally, novel synthesis of oxazaborolidine auxiliaries is demonstrated in which unique solutionto- solid …

1,1-enediamines and β-substituted enamines in heterocyclic synthesis
… and ~ -substituted enamines (push-pull olefines) and their reactions, leading to the formation of a number of heterocycles. Various ~-substituted enamines were prepared by a 'one pot synthesis' in which a l,l-enediamine presumably acts as an intermediate. These enamines, various …

Development and exploration of Schiff base ruthenium carbene catalysts for olefin metathesis
… in methanol and the RCM of disubstituted olefines. We also attempted to synthesize the bimetallic Schiff base substituted Grubbs catalysts, though we showed that here also the previous account of these catalysts was incorrect. In fact, the catalysts can not be synthesized because a …

Single event microkinetic model for steam cracking of hydrocarbons
… interessante producten. Zo worden lichte olefines gevormd zoals ethyleen, propyleen en butadieen. Tevens ontstaan aromaten en zwaardere bijproducten. De gebruikte koolwaterstofvoedingen gaan van lichte alkanen zoals ethaan en propaan tot complexe koolwaterstofmengsels zoals nafta en …
