Dear All,

We are trying to do a RCM, using first generation Grubbs on bis allyl
urea on both nitrogens there is also a OTHP group. Reaction in DCM room
temperature or reflux (degassed and dry) gives only decomposed starting
material with catalyst load 20 mol%, lower loads only give starting
material. Any suggestions.

Thanks,
