Abstract
On the basis of spectroscopic and structural studies a full catalytic cycle is proposed for the Diels–Alder reaction between methacrolein and cyclopentadiene when the new chiral aquo-complexes (RRu, SRu)-[(η6-p-cymene)Ru(PN)(H2O)][SbF6]2 {PN = (3aS, 8aR)-2-(2-diphenylphosphinophenyl)-3a,8a-dihydroindane[1,2-d]oxazole} are used as catalysts.
