conditions. Good functional group tolerance and up to
quantitative yields were observed. In general the photo-
chemical activation provided the propargylic cyclopropanes in
higher yields. Alternative double bonds proved unreactive. The
identification of two different modes of activation for the
coordinatively saturated ferrate catalyst opens up new
perspectives in the field of Fe-catalysis; some of the ventures
in carbene transfer catalysis are currently under investigation in
our laboratories.
