Abstract

The design of effective asymmetric catalysts remains important as chiral intermediates are crucial in the agrochemical and pharmaceutical industries. 1,2 Most success has been achieved with homogeneous catalysis. In recent years, we have studied the aziridination of alkenes using Cu–bis(oxazoline) complexes pioneered by Evans et al. 3 and we have shown that electrostatic immobilisation of the complex within zeolite HY can produce a heterogeneous catalyst ...
