Does anyone know how viable the trichloroformate group is as a leaving group?

I'm curious about pic related as a safer alternative to phosgene-based syntheses of carbamates. However, the E-eros article only shows it being used either as a chlorocarbene source or being electrophilic at the alpha carbon.
The only references I can find being used as a nucleophile are in old russian articles, using boiling toluene.

It's a long shot, but does anyone have experience with these?
