Abstract

1,2-Ferrocenediylazaphosphinines (1a-c) have been successfully employed as a new class of nucleophilic catalysts for ring-opening of a range of epoxides, their catalytic efficiency in terms of regioselectivity as well as chemical yield comparing well with the existing catalysts in the literature. In contrast, low enantiomeric excesses have been obtained from the reactions of meso-epoxides catalyzed by (R)-1.

Key words

ferrocenediylazaphosphinines - nucleophilic catalysts - ring-opening - epoxides

The same reaction, however, did not proceed at all by replacing TMSCl with TMSCN for an unknown reason, as confirmed by quantitative recovery of the starting compound on GC after 24 h.
